To use it, do the following:
Start fem_src_help, and give the name of your source file and the output file when prompted. (You should use the extension .html for the output file.)
You can then use this file by directly loading it into Mosaic with the Open Local menu option, or more conveniently define a link to it from your personal home page, if you have one.
Note that you should never specify the same intput and output file names. The output file is not a valid C++ program.
At the moment, the help compiler is very incomplete and naive; it simply searches for literal strings. If there is demand, I might make it a bit smarter.
