Note that ** every directory should start and end with the '/' and that the first ** directory should be "/" to allow a full path as an argument. ** ** The program first check if PATH_INFO contains some information. ** If it does (t.i. man2html/some/thing is used), the program will look ** for a manpage called PATH_INFO in the manpath. ** ** Otherwise the manpath is searched for the specified command line argument, ** where the following options can be used: ** ** name name of manpage (csh, printf, xv, troff) ** section the section (1 2 3 4 5 6 7 8 9 n l 1v ...) ** -M path an extra directory to look for manpages (replaces "/") ** ** If man2html finds multiple manpages that satisfy the options, an index ** is displayed and the user can make a choice. If only one page is ** found, that page will be displayed. ** ** 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 ** ^^^^ ** 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 Also out of date pages ** might point to incorrect places.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.)
