# build-and-patch.sh — build the Mono.Cecil patcher and patch the Flex API
# license gate in one shot.
#
# Usage:
#   ./build-and-patch.sh [path-to-OpenOptions.dnaFusion.Flex.Common.dll] [softkey]
#
# Defaults:
#   dll     = <script dir>/../../OpenOptions.dnaFusion.Flex.Common.dll
#   softkey = FLEXSTUB
#
# The script builds PatchLicense.cs into a throwaway dotnet project, runs it
# against the target DLL (backing it up to <dll>.orig first), and prints a
# summary. Restart the Flex service afterwards.
