/**
* CGI Servlet.
*
* The cgi bin directory can be set with the "cgibinResourceBase" init parameter
* or it will default to the resource base of the context.
*
* The "commandPrefix" init parameter may be used to set a prefix to all
* commands passed to exec. This can be used on systems that need assistance to
* execute a particular file type. For example on windows this can be set to
* "perl" so that perl scripts are executed.
*
* The "Path" init param is passed to the exec environment as PATH. Note: Must
* be run unpacked somewhere in the filesystem.
*
* Any initParameter that starts with ENV_ is used to set an environment
* variable with the name stripped of the leading ENV_ and using the init
* parameter value.
*
* Based on org.eclipse.jetty.servlets.CGI
