tests: demonstrate broken manifest generation with the pure module
This will be fixed next. But I don't fully understand how 'b.txt' is actually
removed properly in the second test, given what's broken. Also, I'm not sure
why 'bb.txt' is flagged as not being in the manifest, when it clearly appears
to be.
Mercurial's documentation is kept in reStructuredText format, which is
a simple plain text format that's easy to read and edit:
http://docutils.sourceforge.net/rst.html
It's also convertible to a variety of other formats including standard
UNIX man page format and HTML. You'll need to install Docutils:
http://docutils.sourceforge.net/
Use the Makefile in this directory to generate the man and HTML pages.
