# This perl script parses the input file for special variables
# in the format of $Variable$ and replace it with the appropriate
# value(s).
#
# Input: .it file
#             - which is a .ini template
#
#        version
#             - version to display on the blue background
#
#        Path to staging area
#             - path on where the seamonkey built bits are staged to
#
#        xpi path
#             - path on where xpi files will be located at
#
#        redirect file url
#             - url to where the redirect.ini file will be staged at.
#               Either ftp:// or http:// can be used
#               ie: ftp://ftp.netscape.com/pub/seamonkey
#
#        xpi url
#             - url to where the .xpi files will be staged at.
#               Either ftp:// or http:// can be used
#               ie: ftp://ftp.netscape.com/pub/seamonkey/xpi
