This is a helper script to generate the Doxygen documentation. It can be
run in 'liblzma' or 'internal' mode by setting the first argument. It
will default to 'liblzma' mode and only generate documentation for the
liblzma API header files.
The helper script will be run during the custom mydist hook when we
create releases. This hook already alters the source directory, so its
fine to do it here too. This way, we can include the Doxygen generated
files in the distrubtion and when installing.
In 'liblzma' mode, the JavaScript is stripped from the .html files and
the .js files are removed. This avoids license hassle from jQuery and
other libraries that Doxygen 1.9.6 puts into jquery.js in minified form.
Instead of having Doxyfile.in configured by Autoconf, the Doxyfile
can have the tags that need to be configured piped into the doxygen
command through stdin with the overrides after Doxyfile's contents.
Going forward, the documentation should be generated in two different
modes: liblzma or internal.
liblzma is useful for most users. It is the documentation for just
the liblzma API header files. This is the default.
internal is for people who want to understand how xz and liblzma work.
It might be useful for people who want to contribute to the project.
