+GSHHG for Debian
+----------------
+
+The GSHHG data set is composed of three different datasets, and it's
+distributed in NetCDF 4 format, ESRI shapefile and native binary files.
+
+The gmt-gshhg Debian package includes the GSHHG data set in NetCDF 4 format
+for use with GMT 5. It succeeds the gmt-gshhs package, the upstream project
+was renamed starting with version 2.2.1.
+
+Regarding the composition of the GSHHG data set, the projects homepage [1]
+documents the following:
+
+"
+ We present a high-resolution geography data set amalgamated from three
+ data bases in the public domain:
+
+  1.  World Vector Shorelines (WVS).
+      http://shoreline.noaa.gov/data/datasheets/wvs.html
+  2.  CIA World Data Bank II (WDBII).
+      http://www.evl.uic.edu/pape/data/WDB
+  3.  Atlas of the Cryosphere (AC).
+      http://nsidc.org/data/atlas/
+
+ The WVS is our basis for shorelines except for Antarctica while the
+ WDBII is the basis for lakes, although there are instances where
+ differences in coastline representations necessitated adding WDBII
+ islands to GSHHG. The WDBII source also provides all political borders
+ and rivers. The addition of AC since 2.3.0 allows us to offer two
+ choices for Antarctica coastlines: Ice-front or Grounding line. These
+ are encoded as levels 5 and 6, respectively and users of GSHHG can
+ choose which set to use. GSHHG data have undergone extensive
+ processing and should be free of internal inconsistencies such as
+ erratic points and crossing segments. The shorelines are constructed
+ entirely from hierarchically arranged closed polygons.
