# This perl script creates .xpi files given component input name
#
# Input: component name
#             - name of the component directory located in the staging path
#        staging path
#             - path to where the built files are staged at
#        dest path
#             - path to where the .xpi files are are to be created at.
#               ** MUST BE AN ABSOLUTE PATH, NOT A RELATIVE PATH **
#
#   ie: perl makexpi.pl core z:\exposed\windows\32bit\en\5.0
