At the moment it will add links as follows, where * indicates what should match to start with: * ^^^ * Recognition Item Link * ---------------------------------------------------------- * name(*) Manpage ../man?/name.* * ^ * name@hostname Email address mailto:name@hostname * ^ * method://string URL method://string * ^^^ * www.host.name WWW server http://www.host.name * ^^^^ * ftp.host.name FTP server ftp://ftp.host.name * ^^^^ * Include file file:/usr/include/file.h * ^^^ * * Since man2html does not check if manpages, hosts or email addresses exist, * some links might not work. 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 Also out of date pages * might point to incorrect places.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
)
 *  * Some pages look beter if man2html works in troff mode, especially pages
 *    with tables. You can deside at compile time which made you want to use.
 *
 *    -DNROFF=0     troff mode
 *    -DNROFF=1     nroff mode   (default)
 *
 *    if you install both modes, you should compile with the correct CGIBASE.
 *  * Some manpages rely on the fact that troff/nroff is used to convert
 *    them and use features which are not descripted in the man manpages.
 *    (definitions, calculations, conditionals, requests). I can't guarantee
 *    that all these features work on all manpages. (I didn't have the
 *    time to look through all the available manpages.)
