* 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 Also out of date pages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 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.)

// I have corrected that by adding an extra parameter 'next_line' that returns a
// pointer to the next line, while the function itself returns a pointer to the end
// of the last word.
