Considering the discussion of licensing, I think it would be a good idea
if our websites contained a page on licensing and use. This should be a
separate page with a link to it on the home page to make it stand out.
It might go something like this:
liblouis, liblouisxml and their associated programs are open-source and
are free for anyone to download and use according to the following
terms.
1. liblouis and liblouisxml are libraries licensed under the Lesser (or
Library) Gnu Public License (LGPL). Anyone can link to them without
restrictions on the licensing of the calling program. This is already
done by some proprietary packages. Their code can only be modified under
the terms of the LGPL. The tables and files which they use are also
under the LGPL.
2. the liblouis tools (lou_checktable, lou_debug, etc.) are discrete
programs which link to the liblouis library. They are licensed under the
Gnu Public License (GPL), so that they can use code enhancemenss which
are also licensed under the GPL. Anyone can include them in a package
without interfering with the licensing of other components of the
package. They may be called from other programs with command-line
arguments, but may not be linked to. They are unsuitable for linking in
any case.
3. The above comments apply also to the command-line interface to
liblouisxml called xml2brl . It may be called from a GUI or other
program with command-line arguments without affecting the licensing of
the calling ppogram. This is already done by some packages.
