+     The Initial Developer hereby grants You a world-wide, royalty-free,
+     non-exclusive license, subject to third party intellectual property
+     claims:
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Initial Developer to use, reproduce,
+          modify, display, perform, sublicense and distribute the Original
+          Code (or portions thereof) with or without Modifications, and/or
+          as part of a Larger Work; and
+
+          (b) under Patents Claims infringed by the making, using or
+          selling of Original Code, to make, have made, use, practice,
+          sell, and offer for sale, and/or otherwise dispose of the
+          Original Code (or portions thereof).
+
+          (c) the licenses granted in this Section 2.1(a) and (b) are
+          effective on the date Initial Developer first distributes
+          Original Code under the terms of this License.
+
+          (d) Notwithstanding Section 2.1(b) above, no patent license is
+          granted: 1) for code that You delete from the Original Code; 2)
+          separate from the Original Code;  or 3) for infringements caused
+          by: i) the modification of the Original Code or ii) the
+          combination of the Original Code with other software or devices.
+
+     2.2. Contributor Grant.
+     Subject to third party intellectual property claims, each Contributor
+     hereby grants You a world-wide, royalty-free, non-exclusive license
+
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Contributor, to use, reproduce, modify,
+          display, perform, sublicense and distribute the Modifications
+          created by such Contributor (or portions thereof) either on an
+          unmodified basis, with other Modifications, as Covered Code
+          and/or as part of a Larger Work; and
+
+          (b) under Patent Claims infringed by the making, using, or
+          selling of  Modifications made by that Contributor either alone
+          and/or in combination with its Contributor Version (or portions
+          of such combination), to make, use, sell, offer for sale, have
+          made, and/or otherwise dispose of: 1) Modifications made by that
+          Contributor (or portions thereof); and 2) the combination of
+          Modifications made by that Contributor with its Contributor
+          Version (or portions of such combination).
+
+          (c) the licenses granted in Sections 2.2(a) and 2.2(b) are
+          effective on the date Contributor first makes Commercial Use of
+          the Covered Code.
+
+          (d)    Notwithstanding Section 2.2(b) above, no patent license is
+          granted: 1) for any code that Contributor has deleted from the
+          Contributor Version; 2)  separate from the Contributor Version;
+          3)  for infringements caused by: i) third party modifications of
+          Contributor Version or ii)  the combination of Modifications made
+          by that Contributor with other software  (except as part of the
+          Contributor Version) or other devices; or 4) under Patent Claims
+          infringed by Covered Code in the absence of Modifications made by
+          that Contributor.
+
+3. Distribution Obligations.
+
+     3.1. Application of License.
+     The Modifications which You create or to which You contribute are
+     governed by the terms of this License, including without limitation
+     Section 2.2. The Source Code version of Covered Code may be
+     distributed only under the terms of this License or a future version
+     of this License released under Section 6.1, and You must include a
+     copy of this License with every copy of the Source Code You
+     distribute. You may not offer or impose any terms on any Source Code
+     version that alters or restricts the applicable version of this
+     License or the recipients' rights hereunder. However, You may include
+     an additional document offering the additional rights described in
+     Section 3.5.
+
+     3.2. Availability of Source Code.
+     Any Modification which You create or to which You contribute must be
+     made available in Source Code form under the terms of this License
+     either on the same media as an Executable version or via an accepted
+     Electronic Distribution Mechanism to anyone to whom you made an
+     Executable version available; and if made available via Electronic
+     Distribution Mechanism, must remain available for at least twelve (12)
+     months after the date it initially became available, or at least six
+     (6) months after a subsequent version of that particular Modification
+     has been made available to such recipients. You are responsible for
+     ensuring that the Source Code version remains available even if the
+     Electronic Distribution Mechanism is maintained by a third party.
+
+     3.3. Description of Modifications.
+     You must cause all Covered Code to which You contribute to contain a
+     file documenting the changes You made to create that Covered Code and
+     the date of any change. You must include a prominent statement that
+     the Modification is derived, directly or indirectly, from Original
+     Code provided by the Initial Developer and including the name of the
+     Initial Developer in (a) the Source Code, and (b) in any notice in an
+     Executable version or related documentation in which You describe the
+     origin or ownership of the Covered Code.
+
+     3.4. Intellectual Property Matters
+          (a) Third Party Claims.
+          If Contributor has knowledge that a license under a third party's
+          intellectual property rights is required to exercise the rights
+          granted by such Contributor under Sections 2.1 or 2.2,
+          Contributor must include a text file with the Source Code
+          distribution titled "LEGAL" which describes the claim and the
+          party making the claim in sufficient detail that a recipient will
+          know whom to contact. If Contributor obtains such knowledge after
+          the Modification is made available as described in Section 3.2,
+          Contributor shall promptly modify the LEGAL file in all copies
+          Contributor makes available thereafter and shall take other steps
+          (such as notifying appropriate mailing lists or newsgroups)
+          reasonably calculated to inform those who received the Covered
+          Code that new knowledge has been obtained.
+
+          (b) Contributor APIs.
+          If Contributor's Modifications include an application programming
+          interface and Contributor has knowledge of patent licenses which
+          are reasonably necessary to implement that API, Contributor must
+          also include this information in the LEGAL file.
+
+               (c)    Representations.
+          Contributor represents that, except as disclosed pursuant to
+          Section 3.4(a) above, Contributor believes that Contributor's
+          Modifications are Contributor's original creation(s) and/or
+          Contributor has sufficient rights to grant the rights conveyed by
+          this License.
+
+     3.5. Required Notices.
+     You must duplicate the notice in Exhibit A in each file of the Source
+     Code.  If it is not possible to put such notice in a particular Source
+     Code file due to its structure, then You must include such notice in a
+     location (such as a relevant directory) where a user would be likely
+     to look for such a notice.  If You created one or more Modification(s)
+     You may add your name as a Contributor to the notice described in
+     Exhibit A.  You must also duplicate this License in any documentation
+     for the Source Code where You describe recipients' rights or ownership
+     rights relating to Covered Code.  You may choose to offer, and to
+     charge a fee for, warranty, support, indemnity or liability
+     obligations to one or more recipients of Covered Code. However, You
+     may do so only on Your own behalf, and not on behalf of the Initial
+     Developer or any Contributor. You must make it absolutely clear than
+     any such warranty, support, indemnity or liability obligation is
+     offered by You alone, and You hereby agree to indemnify the Initial
+     Developer and every Contributor for any liability incurred by the
+     Initial Developer or such Contributor as a result of warranty,
+     support, indemnity or liability terms You offer.
+
+     3.6. Distribution of Executable Versions.
+     You may distribute Covered Code in Executable form only if the
+     requirements of Section 3.1-3.5 have been met for that Covered Code,
+     and if You include a notice stating that the Source Code version of
+     the Covered Code is available under the terms of this License,
+     including a description of how and where You have fulfilled the
+     obligations of Section 3.2. The notice must be conspicuously included
+     in any notice in an Executable version, related documentation or
+     collateral in which You describe recipients' rights relating to the
+     Covered Code. You may distribute the Executable version of Covered
+     Code or ownership rights under a license of Your choice, which may
+     contain terms different from this License, provided that You are in
+     compliance with the terms of this License and that the license for the
+     Executable version does not attempt to limit or alter the recipient's
+     rights in the Source Code version from the rights set forth in this
+     License. If You distribute the Executable version under a different
+     license You must make it absolutely clear that any terms which differ
+     from this License are offered by You alone, not by the Initial
+     Developer or any Contributor. You hereby agree to indemnify the
+     Initial Developer and every Contributor for any liability incurred by
+     the Initial Developer or such Contributor as a result of any such
+     terms You offer.
+
+     3.7. Larger Works.
+     You may create a Larger Work by combining Covered Code with other code
+     not governed by the terms of this License and distribute the Larger
+     Work as a single product. In such a case, You must make sure the
+     requirements of this License are fulfilled for the Covered Code.
+
+4. Inability to Comply Due to Statute or Regulation.
+
+     If it is impossible for You to comply with any of the terms of this
+     License with respect to some or all of the Covered Code due to
+     statute, judicial order, or regulation then You must: (a) comply with
+     the terms of this License to the maximum extent possible; and (b)
+     describe the limitations and the code they affect. Such description
+     must be included in the LEGAL file described in Section 3.4 and must
+     be included with all distributions of the Source Code. Except to the
+     extent prohibited by statute or regulation, such description must be
+     sufficiently detailed for a recipient of ordinary skill to be able to
+     understand it.
+
+5. Application of this License.
+
+     This License applies to code to which the Initial Developer has
+     attached the notice in Exhibit A and to related Covered Code.
+
+6. Versions of the License.
+
+     6.1. New Versions.
+     Netscape Communications Corporation ("Netscape") may publish revised
+     and/or new versions of the License from time to time. Each version
+     will be given a distinguishing version number.
+
+     6.2. Effect of New Versions.
+     Once Covered Code has been published under a particular version of the
+     License, You may always continue to use it under the terms of that
+     version. You may also choose to use such Covered Code under the terms
+     of any subsequent version of the License published by Netscape. No one
+     other than Netscape has the right to modify the terms applicable to
+     Covered Code created under this License.
+
+     6.3. Derivative Works.
+     If You create or use a modified version of this License (which you may
+     only do in order to apply it to code which is not already Covered Code
+     governed by this License), You must (a) rename Your license so that
+     the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
+     "MPL", "NPL" or any confusingly similar phrase do not appear in your
+     license (except to note that your license differs from this License)
+     and (b) otherwise make it clear that Your version of the license
+     contains terms which differ from the Mozilla Public License and
+     Netscape Public License. (Filling in the name of the Initial
+     Developer, Original Code or Contributor in the notice described in
+     Exhibit A shall not of themselves be deemed to be modifications of
+     this License.)
+
+7. DISCLAIMER OF WARRANTY.
+
+     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+     WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
+     DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
+     IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
+     YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
+     COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
+     OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
+     ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+8. TERMINATION.
+
+     8.1.  This License and the rights granted hereunder will terminate
+     automatically if You fail to comply with terms herein and fail to cure
+     such breach within 30 days of becoming aware of the breach. All
+     sublicenses to the Covered Code which are properly granted shall
+     survive any termination of this License. Provisions which, by their
+     nature, must remain in effect beyond the termination of this License
+     shall survive.
+
+     8.2.  If You initiate litigation by asserting a patent infringement
+     claim (excluding declatory judgment actions) against Initial Developer
+     or a Contributor (the Initial Developer or Contributor against whom
+     You file such action is referred to as "Participant")  alleging that:
+
+     (a)  such Participant's Contributor Version directly or indirectly
+     infringes any patent, then any and all rights granted by such
+     Participant to You under Sections 2.1 and/or 2.2 of this License
+     shall, upon 60 days notice from Participant terminate prospectively,
+     unless if within 60 days after receipt of notice You either: (i)
+     agree in writing to pay Participant a mutually agreeable reasonable
+     royalty for Your past and future use of Modifications made by such
+     Participant, or (ii) withdraw Your litigation claim with respect to
+     the Contributor Version against such Participant.  If within 60 days
+     of notice, a reasonable royalty and payment arrangement are not
+     mutually agreed upon in writing by the parties or the litigation claim
+     is not withdrawn, the rights granted by Participant to You under
+     Sections 2.1 and/or 2.2 automatically terminate at the expiration of
+     the 60 day notice period specified above.
+
+     (b)  any software, hardware, or device, other than such Participant's
+     Contributor Version, directly or indirectly infringes any patent, then
+     any rights granted to You by such Participant under Sections 2.1(b)
+     and 2.2(b) are revoked effective as of the date You first made, used,
+     sold, distributed, or had made, Modifications made by that
+     Participant.
+
+     8.3.  If You assert a patent infringement claim against Participant
+     alleging that such Participant's Contributor Version directly or
+     indirectly infringes any patent where such claim is resolved (such as
+     by license or settlement) prior to the initiation of patent
+     infringement litigation, then the reasonable value of the licenses
+     granted by such Participant under Sections 2.1 or 2.2 shall be taken
+     into account in determining the amount or value of any payment or
+     license.
+
+     8.4.  In the event of termination under Sections 8.1 or 8.2 above,
+     all end user license agreements (excluding distributors and resellers)
+     which have been validly granted by You or any distributor hereunder
+     prior to termination shall survive termination.
+
+9. LIMITATION OF LIABILITY.
+
+     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
+     DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
+     OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
+     ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
+     CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
+     WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
+     COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
+     INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
+     LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
+     RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
+     PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
+     EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
+     THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
+
+10. U.S. GOVERNMENT END USERS.
+
+     The Covered Code is a "commercial item," as that term is defined in
+     48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
+     software" and "commercial computer software documentation," as such
+     terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
+     C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),
+     all U.S. Government End Users acquire Covered Code with only those
+     rights set forth herein.
+
+11. MISCELLANEOUS.
+
+     This License represents the complete agreement concerning subject
+     matter hereof. If any provision of this License is held to be
+     unenforceable, such provision shall be reformed only to the extent
+     necessary to make it enforceable. This License shall be governed by
+     California law provisions (except to the extent applicable law, if
+     any, provides otherwise), excluding its conflict-of-law provisions.
+     With respect to disputes in which at least one party is a citizen of,
+     or an entity chartered or registered to do business in the United
+     States of America, any litigation relating to this License shall be
+     subject to the jurisdiction of the Federal Courts of the Northern
+     District of California, with venue lying in Santa Clara County,
+     California, with the losing party responsible for costs, including
+     without limitation, court costs and reasonable attorneys' fees and
+     expenses. The application of the United Nations Convention on
+     Contracts for the International Sale of Goods is expressly excluded.
+     Any law or regulation which provides that the language of a contract
+     shall be construed against the drafter shall not apply to this
+     License.
+
+12. RESPONSIBILITY FOR CLAIMS.
+
+     As between Initial Developer and the Contributors, each party is
+     responsible for claims and damages arising, directly or indirectly,
+     out of its utilization of rights under this License and You agree to
+     work with Initial Developer and Contributors to distribute such
+     responsibility on an equitable basis. Nothing herein is intended or
+     shall be deemed to constitute any admission of liability.
+
+13. MULTIPLE-LICENSED CODE.
+
+     Initial Developer may designate portions of the Covered Code as
+     "Multiple-Licensed".  "Multiple-Licensed" means that the Initial
+     Developer permits you to utilize portions of the Covered Code under
+     Your choice of the NPL or the alternative licenses, if any, specified
+     by the Initial Developer in the file described in Exhibit A.

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If at some point `config.cache'
+contains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' if you want to change
+it or regenerate `configure' using a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the `configure' script does not know about.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have to compile the package for one architecture at a time
+in the source code directory.  After you have installed the package for
+one architecture, use `make distclean' before reconfiguring for another
+architecture.
+
+Installation Names
+==================
+
+   By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+   Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+   There may be some features `configure' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+Sharing Defaults
+================
+
+   If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+librasterlite2 is an open source library that stores and retrieves huge 
+raster coverages using a SpatiaLite DBMS.
+
+Important notice: this is a brand new project intended to completely 
+replace the superseded librasterlite.
+The two projects are completely unrelated: the unique similarity 
+between both is just in covering the same identical application area.
+
+License: librasterlite2 (the library itself) is licensed under the 
+MPL tri-license terms; you are free to choose the best-fit license 
+between:
+
+    the MPL 1.1
+    the GPL v2.0 or any subsequent version
+    the LGPL v2.1 or any subsequent version
+
+Please note well: anyway the tools supporting the library (both 
+rl2tool and wmslite are licensed under the GPL v3 (or any subsequent 
+version) terms. 
+
+
+Coverage testing
+----------------
+librasterlite2 has coverage testing support. 
+You need to have gcov and lcov installed.
+
+Process:
+1. Use --enable-gcov=yes with configure script
+2. Clean and rebuild.
+3. make coverage-init
+4. make check (or whatever other tests you want to check coverage for)
+5. make coverage
+6. check summary on command line output.
+7. review detailed coverage results in covresults/index.html

+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir

+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+# Configuration subroutine to validate and canonicalize a configuration type.
+# Supply the specified configuration type as an argument.
+# If it is invalid, we print an error message on stderr and exit with code 1.
+# Otherwise, we print the canonical config type on stdout and succeed.
+
+# You can get the latest version of this script from:
+# http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD
+
+# This file is supposed to be the same for all GNU packages
+# and recognize all the CPU types, system types and aliases
+# that are meaningful with *any* GNU software.
+# Each package is responsible for reporting which valid configurations
+# it does not support.  The user should be able to distinguish
+# a failure to support a valid configuration from a meaningless
+# configuration.
+
+# The goal of this file is to map all the various variations of a given
+# machine specification into a single specification in the form:
+#	CPU_TYPE-MANUFACTURER-OPERATING_SYSTEM
+# or in some cases, the newer four-part form:
+#	CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
+# It is wrong to echo any other type of specification.

+\`configure' configures librasterlite2 1.0.0-rc0 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH

+/** \example test_xl.c
+
+test_xl.c is a simple demonstration and diagnostic tool for the Excel (.xls)
+file format.
+
+This sample code provides an example of:
+ - opening the .xls file
+ - querying general information
+ - querying Workbooks, SST entries and FAT entries
+ - error handling
+ - closing the .xls file when no further operations are required
+ 
+Here is an example of a typical run:
+\verbatim
+./test_xl multi.xls
+
+Excel document: multi.xls

+CFBF Version ........: 3
+CFBF Sector size ....: 512
+CFBF FAT entries ....: 128

+BIFF Max record size : 8224
+BIFF DateMode .......: 0 [day#1 = '1900-01-01']
+BIFF Password/Crypted: NO, clear data
+BIFF CodePage .......: UTF-16LE [Unicode]
+BIFF Worksheets .....: 2
+BIFF SST entries ....: 24
+BIFF Formats ........: 2

+
+  1] Yet another
+        ok, Worksheet succesfully selected: currently active: 1
+        302 Rows X 4 Columns
+\endverbatim
+
+Here is another example. Note that this earlier version (Excel 3.0) format
+does not use the CFBF container, so no information is provided for the first
+three entries.
+\verbatim
+# ./test_xl v3sample.xls
+
+Excel document: v3sample.xls

+
+For more information, or to aid with debugging, you can specify a -verbose
+flag, as shown in this example:

+/** \example xl2sql.c
+
+xl2sql a simple tool that takes an .xls file as input, and generates a SQL
+script as output. You can then use the SQL script to load the extracted data
+info a SQLite / SpatiaLite database.
+
+Here is a typical usage example:
+\verbatim
+./xl2sql comuni_italiani.xls >comuni.sql
+spatialite italy.sqlite <comuni.sql
+\endverbatim
+
+The first command will parse the .xls document, extracting any data and
+generating the corresponding SQL script. The second command will create and
+populate a database from the SQL script. When using xl2sql this way, the first
+worksheet will become database table xl_table_00, the second worksheet will
+become database table xl_table_01 and so on.
+
+As an alternative, if you pass a second argument to xl2sql, this argument will
+be used as the table prefix. For example:
+\verbatim
+./xl2sql comuni_italiani.xls italia >comuni.sql
+spatialite italy2.sqlite <comuni.sql
+\endverbatim
+
+This will result in the tables being named italia_00, italia_01 and so on.
+
+This sample code provides an example of:
+ - selecting a worksheet to be active
+ - retrieving cell values

+\section Introduction
+
+FreeXL is an open source library to extract valid data from within an Excel
+(.xls) spreadsheet.
+
+The FreeXL design goals are:
+ - to be simple and lightweight
+ - to be stable, robust and efficient
+ - to be easily and universally portable.
+ - completely ignore any GUI-related oddity
+ 
+Note that the final goal means that FreeXL ignores at all fonts, sizes and
+alignments, and most formats. It ignores Pivot Table, Charts, Formulas, Visual
+Basic macros and so on.
+
+FreeXL is structurally simple and quite light-weight (typically 40-80K of object
+code, stripped). FreeXL has one key dependency - GNU libiconv, which is used for
+character set conversions. This is often provided as part of the C library on
+Linux systems, and is widely available.
+
+Building and installing FreeXL is straightforward:
+\verbatim
+./configure
+make
+make install
+\endverbatim
+
+Linking FreeXL to your own code is usually simple:
+\verbatim
+gcc my_program.c -o my_program -lfreexl 
+\endverbatim
+
+On some systems you may have to provide a slightly more complex arrangement:
+\verbatim
+gcc -I/usr/local/include my_program.c -o my_program \
+  -L/usr/local/lib -lfreexl -liconv -lm
+\endverbatim
+
+FreeXL also provides pkg-config support, so you can also do:
+\verbatim
+gcc -I/usr/local/include my_program.c -o my_program `pkg-config --libs freexl`
+\endverbatim
+
+I sincerely hope FreeXL could be useful to many of you. Excel *.xls spreadsheets
+are widespread, and although Microsoft itself is strongly pushing the new XML
+based formats, there is still a lot of legacy data stored in the older binary
+formats.
+
+So in an era of open data, a simple and easy way to extract data from .xls is
+surely useful. The original use of FreeXL was to support the SQLite /
+SpatiaLite VirtualXL driver (implementing direct access to .xls files via SQL).
+However there are many other possibilities, including use with shell scripts and
+simple wrappers for Python, Perl and other very high level languages.
+
+FreeXL is licensed under the MPL tri-license terms: you are free to choose the
+best-fit license between:
+ - the MPL 1.1 
+ - the GPL v2.0 or any subsequent version
+ - the LGPL v2.1  or any subsequent version
+
+Enjoy, and happy coding

+
+/** \page Origins The background story for FreeXL
+
+Where, when and why a new free software library was born...
+
+At the end of April 2011 Markus Neteler
+[http://en.wikipedia.org/wiki/Markus_Neteler] and I (Sandro) were in Udine in
+Northern Italy, attending the annual Italian gvSIG Users conference. So, on a
+lovely hot and sunny spring evening, accompanied by a picturesque sunset, we
+were sitting in the town centre in the pleasant Piazza Matteotti aka Piazza San
+Giacomo, peacefully drinking some spritz while eating chips and peanuts.
+

+\image latex piazza.eps "Piazza" width=12cm
+
+You'll have to admit, it was a really dangerous situation: as a general safety
+rule, never let two developers sit idle for too long. Some odd and crazy idea
+will inevitably occur to them  (of course, drinking too much spritz can 
+contribute as well).
+
+Markus was desperately attempting to convince me that implementing a
+VirtualTable driver for SpatiaLite supporting direct SQL reading ofExcel .xls
+files was a good initiative. Surely it would be useful for many users. I
+strongly resisted, fiercely fighting and rejecting such idea, on the basis that
+attempting to read proprietary closed formats such as Excel was a complete
+nonsense, and probably a very difficult if not impossible task.
+ 
+At the end of this very animated discussion, Markus pronounced the magic spell
+that suddenly convinced me about the absolute validity of his suggestions:
+<em>I can raise some funding for this project</em> After hearing such wise and
+significant words from Markus I immediately realized that developing a new
+driver for accessing Excel .xls documents surely was an exciting and useful task
+after all.
+
+So FreeXL / VirtualXL was conceived at that exact moment, and slowly 
+began its development cycle.

+/** \page Specs File format specifications and source information
+
+The .xls binary file format is extensively documented and is publicly available.
+The most authoritative source is made available by Microsoft at
+http://msdn.microsoft.com/en-us/library/cc313154%28v=office.12%29.aspx
+
+A simpler option is made available by Open Office:
+http://sc.openoffice.org/excelfileformat.pdf
+
+Searching the web you'll easily find several other valuable information sources.

+
+/** \page Format About the .xls binary format
+
+What a .xls binary file really is 
+
+(Prepare yourself to be continuously surprised by many unexpected revelations
+...)
+
+You may already know that there are many different versions of .xls files.
+Different versions have different capabilities. So we'll start by
+reviewing the Excel evolutionary history and and we'll introduce some Microsoft
+jargon because it's central to understanding the underlying operations.
+
+\section CFBF CFBF
+
+Unexpected Revelation #1:
+<em>There is no .xls file format. Its really a common file suffix applied to
+many different things.</em>
+
+Recent Microsoft Office document files are based on a common container layout
+named CFBF (Compound File Binary Format). This container format is the same for
+Excel (.xls), Word (.doc_ and PowerPoint (.ppt) amongst other applications.
+More information:
+ - http://en.wikipedia.org/wiki/Compound_File_Binary_Format
+ - http://msdn.microsoft.com/en-us/library/dd942138%28v=prot.13%29.aspx 
+
+Unexpected Revelation #2:
+<em>CFBF  is more of a file system than a file format</em>
+
+A CFBF file is divided into many equal-sized blocks named sectors.
+Such sectors cannot be directly accessed. In order to retrieve sectors in the
+expected logical order a FAT (File Allocation Table) is allocated within 
+the CFBF file. A CFBF file is internally organized as if it was a raw physical
+disk. The design is based on Microsoft own FAT file-system as used by MS-DOS and
+early versions of Windows. The first sector of the CFBF file acts as if it was a
+kind-of MBR (Master Boot Record) - this first sector provides information about
+the layout and type of the CFBF file, such as block/sector size and version.
+A FAT chain allows a reader to re-assemble the sectors in the required logical
+order. There is a list of free block, and very large files may use a
+double indirection (DIFAT - Double Indirection FAT). A CFBF file always has at
+least a root directory: but a complete directory tree can be provided.
+
+A CFBF file can contain many and many distinct independent files. Just to make
+things a little clearer, Microsoft calls such pseudo-files (I mean: the many
+fake ones contained within the real CFBF file) <em>streams</em>
+
+The practical consequence is that any software tool attempting to access an
+Excel binary document must first be able to correctly access this CFBF 
+container format.
+
+\section BIFF BIFF
+Unexpected Revelation #3:
+<em>An Excel document will contain a stream (pseudo-file) named Workbook in
+the root directory of the CFBF file (filesystem).</em>
+
+The Workbook stream is internally structured accordingly to the BIFF (Binary
+Interchange File Format) specifications. You can think of the BIFF as the real
+Excel binary format (following more conventional naming rules). Several BIFF
+versions were introduced during the years: and there are significant differences
+between them.
+
+An useful correspondence table relating corresponding Excel and BIFF versions:
+
+<table>
+    <tr>
+	<th>
+	    <b>Excel Version</b>
+	</th>
+	<th>
+	    <b>Commercial Name</b>
+	</th>
+	<th>
+	    <b>BIFF Version</b>
+	</th>
+	<th>
+	    <b>Release Year</b>
+	</th>
+	<th>
+	    <b>Notes</b>
+	</th>
+    </tr>
+    <tr>
+	<td>2.x</td>
+	<td>Excel 2.0</td>
+	<td>BIFF2</td>
+	<td>1987</td>
+	<td>Before CFBF. File is the BIFF stream, containing a single
+	worksheet.</td>
+    </tr>
+    <tr>
+	<td>3.0</td>
+	<td>Excel 3.0</td>
+	<td>BIFF3</td>
+	<td>1990</td>
+	<td>Before CFBF. File is the BIFF stream, containing a single

+	<td>BIFF5</td>
+	<td>1993</td>
+	<td>Starting with BIFF5, a single Workbook can internally store many
+	individual Worksheets. The BIFF stream is stored in the CFBF file
+	container.</td>
+    </tr>
+    <tr>
+	<td>7.0</td>
+	<td>Excel 95</td>
+	<td>BIFF5</td>
+	<td>1995</td>
+	<td></td>
+    </tr>
+    <tr>
+	<td>8.0</td>
+	<td>Excel 98</td>
+	<td>BIFF8</td>
+	<td>1998</td>
+	<td></td>
+    </tr>
+    <tr>
+	<td>9.0</td>
+	<td>Excel 2000</td>
+	<td>BIFF8</td>
+	<td>1999</td>
+	<td></td>
+    </tr>
+    <tr>
+	<td>10.0</td>
+	<td>Excel XP</td>
+	<td>BIFF8</td>
+	<td>2001</td>
+	<td></td>
+    </tr>
+    <tr>
+	<td>11.0</td>
+	<td>Excel 2003</td>
+	<td>BIFF8</td>
+	<td>2003</td>
+	<td></td>
+    </tr>
+    <tr>
+	<td>12.0</td>
+	<td>Excel 2007</td>
+	<td>BIFF8</td>
+	<td>2007</td>
+	<td>Introduced alternate XML format, which is usually the default
+	for new files.</td>
+    </tr>
+    <tr>
+	<td>14.0</td>
+	<td>Excel 2010</td>
+	<td>BIFF8</td>
+	<td>2010</td>
+	<td>XML format is usually the default for new files.</td>
+    </tr>
+</table>
+
+Note that FreeXL does not support the new XML format which is a completely
+different and unrelated format.
+
+Perhaps you are now expecting that BIFF will simply and directly encode your
+spreadsheet data. Unfortunately, you should have know better given the steps
+we took to get here...
+
+Unexpected Revelation #4:
+<em>Any BIFF stream (pseudo-file stored within a CFBF container file) is
+internally organized as a collection of variable-length records.</em>.
+
+Each record starts with 
+ - a 16 bit unsigned integer specifying the record type 
+ - another 16 bit unsigned integer specifies the record data length (in bytes)
+ excluding the standard type-size prefix.
+
+Note that there are many different record types, and the record size / layout
+may differ for different BIFF versions.
+
+Three record types have an absolutely special meaning:
+ - a BOF [Beginning Of File] record marks starting of a different sub-stream.
+ - an EOF [End Of File] record marks ending of current sub-stream.
+ - a CONTINUE record means that the previous record exceeded the maximum size
+ for a record, and the previous record data payload will be spanned on 
+ following CONTINUE records for as many CONTINUE records as are required to
+ store the full data size.
+
+Unexpected Revelation #5:
+<em>So a BIFF stream (pseudo-file) isn't really a file - it's more like a
+collection of individual sub-streams, each one of which is enclosed between BOF
+/ EOF markers.</em>
+
+The most recent BIFF8 requires that at least the following internal
+sub-streams are be defined:
+ - the first sub-stream contains workbook level global data and metadata, such
+ as author, password protection, styles, formats, window settings and so on
+ - list of individual worksheets included into the Workbook, where each 
+ worksheet is identified by a name and by a type (data Worksheet, Chart,
+ Visual Basic module ... visible, hidden ...), and relative offset position of
+ the corresponding BOF record allows for fast positioning.
+ - any text string is stored here into the SST [Shared String Table], so
+ individual text cells simply refer the corresponding SST entry by index (in all
+ previous BIFF version text strings are directly stored into the appropriate
+ cell).
+ - any subsequent sub-stream represents a single Worksheet, and the most
+ relevant data stored at Worksheet level are dimension (number of valid rows and
+ columns) and any cell value data.
+
+We will now see how BIFF encodes individual data types with several further
+amazing surprises are still to come. Be prepared!
+
+\section BIFF Supported data types and encoding
+
+Leaving aside special values such as images, OLE, COM, Visual Basic related
+items and so on, the basic data types are supported in BIFF:
+ - text strings
+ - numbers (both integers and decimals)
+ - dates, date-times and times
+ - NULL (empty cell)
+
+Note that any multi-byte value is stored in BIFF accordingly using Little Endian
+byte ordering (i.e. least significant byte comes first, most significant byte
+comes last).
+
+<table>
+    <tr>
+	<th><b>BIFF Record Type</b></th>
+	<th><b>BIFF Version</b></th>
+	<th><b>Content Type</b></th>
+    </tr>
+    <tr>
+	<td>INTEGER</td>
+	<td>BIFF2</td> 
+	<td>16 bit unsigned integer</td>
+    </tr>
+    <tr>
+	<td>NUMBER</td>
+	<td>BIFF2 BIFF3 BIFF4 BIFF5 BIFF8</td>
+	<td>64 bit floating point (double precision)</td>
+    </tr>
+    <tr>
+	<td>RK</td>
+	<td>BIFF3 BIFF4 BIFF5 BIFF8</td>
+	<td>number, variant-type: INTEGER FLOAT DATE DATETIME TIME
+	(please see the corresponding detailed description)</td>
+    </tr>
+    <tr>
+	<td>MULRK</td>
+	<td>BIFF5 BIFF8</td>
+	<td>a variable-sized array of elementary RK values.
+	associated to a range of consecutive cells on the same row </td>
+    </tr>
+    <tr>
+	<td>LABEL</td>
+	<td>BIFF2 BIFF3 BIFF4 BIFF5 BIFF8</td>
+	<td>text string, variable-length.
+	(please see the corresponding detailed description)</td>
+    </tr>
+    <tr>
+	<td>LABELSST</td>
+	<td>BIFF8</td>
+	<td>text string, variable-length. based on the global SST
+	[Shared String Table] stored at the workbook level, so a LABELSST simply
+	requires providing the corresponding SST index.</td>
+    </tr>
+</table>
+
+So the BIFF record type that is easy to handle is NUMBER, which is essentially
+a C-style <em>double</em>. Other record types require additional handling.
+
+\subsection RK RK values
+
+An RK value is a 32 bit value. 
+
+The least significant two bits are a bit-mask (in little endian order, so the 
+least two significant bits in the first byte that is read):
+ - if 0x02 is set the RK value represents a 30 bit signed integer, otherwise it
+ represents a 64 bit floating point double precision number requiring special
+ reconstruction.
+ - if 0x01 is set the corresponding value needs to be divided by 100, so even an
+ integer actually becomes a floating point double precision.
+
+When interpreting RK values as a signed integer, right shifting two bits is
+required:
+\code
+int value = rk_value >> 2;
+\endcode
+
+When interpreting RK values as a 64 bit floating point, two steps are required:
+ - the RK value requires appropriate  masking: 
+\code
+int value = rk_value & 0xfffffffc;
+\endcode
+ - then the 32 bit value will be copied into a 64 bit buffer, and the least
+ significant four bytes need to be initialized as zeroes: 0x00000000.
+
+As a final step, if 0x01 was set into the bit-mask, now we have to divide by
+100 before returning the effective cell value. So for 32 bit integers:
+\code
+double final_value = (double)value / 100.0;
+\endcode
+and for 64 bit floats:
+\code
+double final_value = value / 100.0;
+\endcode
+
+\subsection Text Text values
+
+Any BIFF version from BIFF2 to BIFF5 simply supports CodePage based character
+encoding, i.e. each character simply requires 8 bits to be represented  (single
+byte). Correct representation of characters requires knowing which one CodePage
+table has to be applied. This can be determined from the workbook or
+worksheet metadata (it is the CODEPAGE record).
+
+BIFF8 is much more sophisticated, since any text
+string is usually encoded as Unicode in UTF-16 Little Endian [UTF-16LE] format.
+This encoding is a multi-byte encoding (two bytes are required to represent a
+single character), but being universal no character table is required.
+
+BIFF text strings are never null-terminated. The actual length is always
+explicitly stated, as an 8 bit unsigned int or as a 16 bit unsigned int
+(depending on BIFF versions).
+
+FreeXL is intended to be strictly interoperable with SQLite and SpatiaLite, so
+any text string has to be converted to UTF-8 encoding. GNU libiconv can easily
+handle any required charset conversion. So we can simply fetch the appropriate
+bytes, then call iconv() as appropriate, and we'll immediately get back the
+corresponding UTF-8 encoded text string.
+
+Converting Unicode based text strings is a little more complex, because
+each Unicode string is prefixed by a mask byte, specifying how the string is
+encoded:
+ - if 0x01 is set, then the string really is 16 bit per character Unicode,
+ otherwise a stripped notation is used instead. Stripped notation means
+ that the characters are actually represented as single bytes, so already
+ have the UTF8 equivalent.
+ - if 0x04 and/or 0x08 are set, than some further variable-length data
+ (providing information on text decoration such as italics, bold, underline) is
+ inserted immediately before and after the text string itself, so we must
+ carefully skip over this extra data so to maintain the right byte alignment.
+
+Note that the string length is expressed in characters, not in bytes, so the 
+actual length in bytes is twice the indicated length.
+
+\subsection Dates Retrieving Date, DateTime and Time values.
+
+Dates, DateTimes and Time values are also a little complicated. Any Date is
+expressed as an Integer (number of days since the conventional reference day):
+ - for Windows Excel the reference day (day 0) is 1900, January 1
+ - for Mac Excel the reference day (day 0) is 1904, January 2
+
+There is no possible ambiguity, because the DATEMODE metadata record 
+specifies tells which reference day is to be used.
+
+An odd bug affects Excel, which (incorrectly) treats 1900 as a leap year.
+Therefore, the non-existent 29 February 1900 has to be included in the days
+calculation so to get the expected Date value. 
+
+Any Time is expressed as a Fraction (percent of seconds since midnight).
+0.5 corresponds to 12:00:00 (midday), 0.25 corresponds to 06:00:00, 0.75
+corresponds to 18:00:00 and so on. 
+
+So a DateTime is simply the sum of a Date value and of a Time value. Dates
+can be represented by Integers: but Times and DateTimes require a floating point
+number.
+
+The complication with Dates, DateTimes and Time values is that the data-type
+does not specify when a cell values has to be interpreted as a Date or Time - 
+it is simply an Integer or Float numbers like any other. A further indirection
+has to applied so to correctly recognize Dates, DateTimes and Times:
+ - each NUMBER, RK or MULRK value exposes an index referencing the XF
+(Extended Format) entry associated with the corresponding cell.
+ - each XF record specifies an unique combination of font, alignment, color
+ and so on, however a further indirection specifies the corresponding FORMAT 
+ entry
+ - each FORMAT record specifies an output format, such as M/D/YY, h:mm:ss AM/PM
+ or M/D/YY h:mm: and this finally gives us a good chance to guess which cell
+ values are intended to represent Date/Time values. 
+ 
+Both XF and FORMAT records are globally stored at the Workbook level, and
+represent ordered arrays.
+
+If you haven't yet given up, if you aren't yet become totally mind-boggled,
+and if you are still awake and conscious, then you now know how .xls files
+are internally organized and structured.
+
+Be happy and feel proud of yourself.
+*/
+
+/** \page OtherTools Other tools and libraries
+There an impressively wide choice of Free and open source libraries and tools
+supporting the .xls format. A sample:
+
+ - Gnumeric [http://projects.gnome.org/gnumeric/] seems to be the pioneer of
+them all, and probably was the first FLOSS tool able to read and write .xls
+(circa 2001). Part of the Gnome Office project.
+ - KSpread / Caligra Tables [http://www.calligra-suite.org/tables/] / KCells
+[http://www.koffice.org/kcells/] are similar (but now distinct) programs
+from the KOffice and Calligra Office projects.
+ - Open Office Calc [http://www.openoffice.org/product/calc.html] and
+LibreOffice Calc [http://www.libreoffice.org/features/calc/] are similar
+(but now distinct) spreadsheet applications originally from the StartOffice
+code base. Probably the most comprehensive support in FLOSS.
+ - Apache POI-HSSF [http://poi.apache.org/spreadsheet/index.html] is a
+sophisticated Java library fully supporting .xls files.
+ - JExcelAPI [http://jexcelapi.sourceforge.net/] is another Java library
+(much simpler and lighter than POI-HSSF) supporting .xls files.
+ - several C or C++ libraries exist as well: quite curiously one is named
+libxls and another xlslib, but they are two absolutely distinct and unrelated
+packages
+ - There are other implementations are available based on .NET or PHP.
+
+A quick critical review:
+ - GUI tools implementations are difficult to re-use. They focus on import of
+ all formulas, GUI presentation and so on, which is really a different use.
+ - Java libraries seem to be really interesting, but Java is difficult to call
+ from a C or C++ program.
+ - Several C/C++ libraries exist, but none of them seems to be sufficient and
+  stable as required. Some are still marked to be “beta-stage” despite 
+  being released some four or five years ago - project activity seems to be
+  very low, and download statistics are discouraging.
+
+Conclusion: a suitable C/C++ library supporting data extraction from .xls files
+doesn't seem to exists: or at least, there is no obvious reference choice.
+
+So we'll go on the hardest way, we'll develop yet another .xls reading
+library: FreeXL.
