The cgi-postin utility processes data generated
from a World-Wide Web form. It is a standalone processor that may
be run easily from sh, perl, or
Tcl scripts.
Important Note: I recommend this tool only when
implementing CGIs as shell scripts. For other languages, there
are more modern and suitable tools for the task of CGI processing.
For CGI processing in perl, I recommend the bundled CGI.pm
module. For C, there are a number of packages
available to do the task.
