#
# Example of how to use the Spreadsheet::WriteExcel module to send an Excel
# file to a browser using mod_perl 1 and Apache
#
# This module ties *XLS directly to Apache, and with the correct
# content-disposition/types it will prompt the user to save
# the file, or open it at this location.
#
# This script is a modification of the example cgi.pm script bundled
# with Spreadsheet::WriteExcel.

#
# Change the name of this file to Cgi.pm.
# Change the package location to where-ever you locate this package.
# Below, I have this located in the WriteExcel directory.
#
# Your httpd.conf entry for this module, should you choose to use it
# as a stand alone app, should look similar to the following:
#
# <Location /spreadsheet-test>
# SetHandler perl-script
# PerlHandler Spreadsheet::WriteExcel::Cgi
# PerlSendHeader On
# </Location>
#
# PerlHandler and the package line below have to match.
# I promise.
