# 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
#        URL path
#             - path to where the .xpi files are staged.  can be
#               either ftp:// or http://
#
#   ie: perl makecfgini.pl config.it 5.0.0.1999120608 z:\exposed\windows\32bit\en\5.0 d:\builds\mozilla\dist\win32_0.obj\install\xpi ftp://sweetlou/products/client/seamonkey/windows/32bit/x86/1999-09-13-10-M10
