What we need is two interfaces of SANE, once the frontend/library
interface, so that one can have scanning functionality in LSB-packaged
applications, and second, the library/backend interface to allow
distribution-independent LSB-based scanner driver packages.
The LSB expects also testing code. Usually a program which exercises all
the interfaces which are selected as requirement for the LSB (ideally,
one should require all interfaces of the library).
A test program could look like this:
This is for CUPS but one could do a similar thing for SANE. The test
program should not depend on a particular scanner model. One could
auto-detect a scanner and if none is there use the test backend.
The individual drivers in /usr/lib/sane/ do not need to be tested.
Important are only the interfaces for new drivers and for applications
with scanning functionality.
