For manpages, some extra checks are performed + * to make sure not every () pair creates a link. Also out of date pages + * might point to incorrect places. + * + * The program will not allow users to get system specific files, such as + * /etc/passwd. It will check that "man" is part of the specified file and + * that "/../" isn't. Even if someone manages to get such file, man2html will + * handle it like a manpage and will usually not produce any output (or crash). + * + * If you find any bugs when normal manpages are converted, please report + * them to me (rcb5@win.tue.nl) after you have checked that man(1) can handle + * the manpage correct. + * + * Known bugs and missing features: + * + * * Equations are not converted at all. + * * Tables are converted but some features are not possible in html. + * * The tabbing environment is converted by counting characters and adding + * spaces. This might go wrong (outside <PRE>) + * * Some pages look better if man2html works in troff mode, especially pages + * with tables.

I can't guarantee + * that all these features work on all manpages.
