OMhelp was originally developed by
which has source code in multiple languages.
OMhelp extracts the documentation from the source code
and generates an HTML or XHTML+MATHML
web site that contains the corresponding help files.
It can also be used to create a web site not
related to a program.
It enables you to divide your help or web site into separate files
and to track changes using source code control
(in the case of a program, the same source code control at the same time).
OMhelp makes it easy to build a large help system or web site,
by tracking both internal and external links.
