=head1 NAME

asp-perl - Apache::ASP CGI and command line script processor

=head1 SYNOPSIS

asp-perl [-hsdb] [-f asp.conf] [-o directory] file1 @arguments file2 @arguments ...

    -h  Help you are getting now!
    -f  Specify an alternate configuration file other than ./asp.conf
    -s  Setup $Session and $Application state for script.
    -d  Set to debug code upon errors.
    -b  Only return body of document, no headers.
    -o  Output directory, writes to files there instead of STDOUT
    -p  GlobalPackage config, what perl package are the scripts compiled in.

=head1 DESCRIPTION

This program will run Apache::ASP scripts from the command line.
Each file that is specified will be run, and the 
$Request->QueryString() and $Request->Form() data will be 
initialized by the @arguments following the script file name.  

The @arguments will be written as space separated 
words, and will be initialized as an associate array where
%arguments = @arguments.  As an example:

 asp-perl file.asp key1 value1 key2 value2

would be similar to calling the file.asp in a web environment like

 /file.asp?key1=value1&key2=value2

The asp.conf script will be read from the current directory
for parameters that would be set with PerlSetVar normally under
mod_perl.  For more information on how to configure the asp.conf
file, please see < http://www.apache-asp.org/cgi.html >
