+ * man2html will add links to the converted manpages. The function add_links
+ * is used for that. 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
+ * ^^^^
+ * <file.h> 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 Also out of date pages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 <PRE>)
+ * * 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.)
