This can be used as a stand-alone utility, but is mainly intended as an auxiliary, to enable users to browse their man pages using a html browser like lynx(1), xmosaic(1) or netscape(1).
The main part of man2html is the troff-to-html engine written by Richard Verhoeven (email@example.com). It adds hyperlinks for the following constructs:
(The first of these can be tuned by options - see below.) No lookup is done - the links generated need not exist. Also an index with internal hyperlinks to the various sections is generated, so that it is easier to find ones way in large man pages like bash(1).
|Strip the last two parts from the pathname, and do a chdir(dir) before starting the conversion.|
|The -E option allows the easy generation of error messages from a cgi script.|
|Output an error page containing the given error message.|
|The general form of a hyperlink generated for a man page reference is|
|with a default as shown above. The parts of this hyperlink are set using the various options.|
|-h||Set method:cgipath to http://localhost. This is the default.|
|Set method:cgipath to http://host.domain:port.|
|-l||Set method:cgipath to lynxcgi:/home/httpd.|
|Set method:cgipath to lynxcgi:dir.|
|Set the man2htmlpath to use. The default is /cgi-bin/man/man2html.|
|-p||Set separator to /.|
|-q||Set separator to ?. This is the default.|
|-r||Use relative html paths, instead of cgi-bin paths.|
On a machine without running
httpd, one can use
lynx to browse the man pages, using the lynxcgi method.
When some http daemon is running, lynx, or any other browser,
can be used to browse the man pages, using the http method.
The option -l (for lynxcgi) selects the former behaviour.
With it, the default cgipath is /home/httpd.
In general, a cgi script can be called by
and the environment variables PATH_INFO and QUERY_STRING
will be set to <more_path> and <query>, respectively.
Since lynxcgi does not handle the PATH_INFO part, we generate
hyperlinks with ? as a separator by default.
The option -p (for path) selects / as a separator, while
the option -q (for query) selects ? as a separator.
The option -H host will specify the host to use (instead of localhost). A cgi script could use
|man2html -H $SERVER_NAME|
