<pre>

In order to not have to modify each script when porting CGI scripts to different 
platforms, there ought to be a way to override the shebang line to specify where 
a given CGI app lies.

Proposed syntax in server config, virtual host, .htaccess:
    CGIOverride {<full-path-to-app>|off} <file-ext-list>
or
    ShebangOverride {<full-path-to-app>|off} <file-ext-list>

Eg:
CGIOverride c:/perl/bin/perl.exe .pl .cgi  # override shebang line on .pl and .cgi scripts
CGIOverride off .cgi                       # turn shebang override back off for this dir (.htaccess)

Possibly also:
CGIOverride c:/perl/bin/perl.exe form.pl   # override a single script (probably only used in .htaccess)

</pre>
>How-To-Repeat:

>Fix:
Possible changes to ap_execve.c, util_script.c, mod_cgi.c, etc. to implement, 
plus addition of syntax above.
