Licenses
========

This package contain parts covered by different licenses. These parts are placed
in different subdirectories to separate them.

Every subdirectory contains a 'LICENSE' file that is valid for all files in that
subdirectory. If the subdirectory is used only for structuring, a symbolic link
is used to avoid multiple copies of the same licence.
If a 'LICENSE' file/link should be missing, please report this as bug.

The parts of the top level build system including the subdirectory 'cfg'
(created at runtime) are covered by the license in 'src/LICENSE'.
Exceptions:
The files 'CONFIG' and 'mksyslibs' are intended to customize the program. Any
changes made to these files don't create a modified version of the program in
terms of this license.


Create license overview
=======================

To create a list of all license files, use the command:

   find . ! -type l -name LICENSE

References (via symbolic links) are not shown in this list.


(L)GPL notice
=============

None of the files that are installed by the build system using 'make install'
is covered by the GPL. For the LGPL this is also true because an exception in
the FLTK license allows even for static linking without creating a "derived
work".

The parts in the source tree covered by the GPL are images that are used for the
HTML and PDF documentation only (but not the man page).

For the HTML documentation these parts are "separate works" in the sense of the
GPL, because they are simply referenced by hyperlinks and neither modified nor
embedded.

For the PDF documentation these parts are embedded into the PDF file and may or
may not be modified depending on the LaTeX toolchain of the operating system
used to generate the documentation. Therefore the PDF documentation must be
considered a "derived work" in the sense of the GPL.
If in doubt, ask a lawyer or simply don't (re)distribute the PDF documentation
at all.
