test-merge-types: allow different output with existing hgmerge (issue3346)
Because hgmerge was meant to be adjusted to personal needs, there may be
many remaining copies in people's $PATH.
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.
