# Quick and dirty script to fix up .fsproj build orders 
# to compile under xbuild when enabled in xamarin studio
# 
# this relies on a propper build order set the normal way under
# project options -> general -> build order. Output should be something like
# 
# $ fixorder.rb gitopc/gitopc.fsproj
# Make sure you have set a valid build order in 'Project options -> General -> Build order' before running this script
# Press enter to continue, Ctrl+C to abort.
#
# Changing build order to:
# 0: AssemblyInfo.fs => AssemblyInfo.fs
# 1: Program.fs => Logging.fs
# 2: PrivateKey.fs => PrivateKey.fs
# 3: CDNUtils.fs => EmailUtils.fs
# 4: Logging.fs => OBundleUtils.fs
# 5: EmailUtils.fs => CDNUtils.fs
# 6: OBundleUtils.fs => Program.fs
# Press enter to continue, Ctrl+C to abort.
#
# Backing up gitopc/gitopc.fsproj to gitopc/gitopc.fsproj.backup
# Build order re-ordered!
