# iisinfsp.pl
#
# Perl script
#
# generates iis.inf for service packs from its gold version.
# goldfiles\<lang>\<arch>\iis.inf.gold are checked in files.
# this script pick up changes in iisend.inx, merge into iis.inf.
# it also find changed files from spfiles.txt, edit iis.inf
# so the source disk points to service pack CD.
# lastly, it update cdname section with mednames.txt
#
# the script is designed and tested for WinXP. it runs on two
# platforms: ia64 and x86.
