  * man2html-linux-1.0/1.1
  * This version modified for Redhat/Caldera linux - March 1996.
  * Michael Hamilton <michael@actrix.gen.nz>.
  *
  * man2html-linux-1.2
  * Added support for BSD mandoc pages - I didn't have any documentation
  * on the mandoc macros, so I may have missed some.
  * Michael Hamilton <michael@actrix.gen.nz>.
  *
  * vh-man2html-1.3
  * Renamed to avoid confusion (V for Verhoeven, H for Hamilton).
  *
  * vh-man2html-1.4
  * Now uses /etc/man.config
  * Added support for compressed pages.
  * Added "length-safe" string operations for client input parameters.
  * More secure, -M secured, and client input string lengths checked.

 /*
 ** If you want to use this program for your WWW server, adjust the line
 ** which defines the CGIBASE or compile it with the -DCGIBASE='"..."' option.
 **
 ** You have to adjust the built-in manpath to your local system. 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
 ** ^^^^
 ** <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 manpages rely on the fact that troff/nroff is used to convert
 **    them and use features which are not described 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.)
