########################################################################
# Converts a man page to very simple html, basically a page with
# A and PRE tags. Takes 1 arguments: path to the non-compressed man
# page. This expects the man page to be named PAGE_NAME.SECTION_NUMBER;
# like `PQgetf.3' or `printf.1'.
#
# FEATURES
# 1. Any some_man(3), no spaces before '(', is substituted for an
# A tag linking to http://libpqtypes.esilo.com/man3/$man.html
#
# 2. All '<' and '>' are replaced with HTML codes
#
# 3. Mans referencing other mans, via .so macro, are converted
# to symlinks in the output directory.
#
# ISSUES
# Hyperlinks are not 100% substitued into resulting html page.
# The only time there are issues is when the link text in the
# man page was broken across lines. No work-around at this time
# for this issue other than manually ensuring line breaks don't
# occur on `some_man(3)'.
#
# Man pages that reference other man pages, using the .so macro,
# must have the .so command in the first 'head' lines. The
# .so 'path_to_man' cannot include spaces.
