Haserl is a small cgi wrapper that allows "PHP" style cgi programming,
but uses a UNIX bash-like shell or lua as the programming language. It
is very small, so it can be used in embedded environments, or where
something like PHP is too big.

It combines three features into a small cgi engine: * It parses
POST and GET requests, placing form-elements as name=value
pairs into the environment for the CGI script to use. This is
somewhat like the uncgi wrapper.

* It opens a shell, and translates all text into printable
statements. All text within ... ?> constructs are passed
verbatim to the shell. This is somewhat like writing PHP
scripts.

* It can optionally be installed to drop its permissions to the
owner of the script, giving it some of the security features of suexec
or cgiwrapper.
