Generate text documentation from the troff source files.
This is done by make, in the 'docs' target, which is now part of the
normal build process.
Unfortunately, not all the games include troff sources. Getting decent
HTML output from groff is still a difficult process which will not be
attempted at this time. There are a few bugs in the 'install' and
'uninstall' rules.
Not to mention that the documentation is sometimes inaccurate.
