#
# Steps for making a new xctool release --
#
# 0.  Run ./make_release.sh to make sure it builds and tests pass; do some
#     QA on the version of xctool that it installs.
# 1.  Run `git status` to make sure you're working on a clean copy of master.
# 2.  Bump the version in xctool/xctool/Version.m; commit your change.
# 3.  Tag the branch; e.g. `git tag v0.1.6`
# 4.  Push the version bump; e.g. `git push origin master`
# 5.  Push the tag; e.g. `git push --tags origin`
# 6.  Run ./make_release.sh again to produce the final binary distribution.
# 7.  Go to https://github.com/facebook/xctool/releases/; find the new tag.
# 8.  Click 'Draft release notes and downloads'.
# 9.  Upload the ZIP file produced from make_release.sh.
# 10. Write some release notes - use the compare view to find what's changed.
#     https://github.com/facebook/xctool/compare/v0.1.5...v0.1.6
# 11. Publish!

# We're using a hack to trick otest-shim into building as a dylib for the iOS
# simulator.  Part of that hack requires us to specify paths to the SDK dirs
# ourselves and so we need to know the version numbers for the installed SDK.
# Configurations/iOS-Simulator-Dylib.xcconfig has more info.
#
# We choose the oldest available SDK that's >= 5.0 - this way otest-shim is
# most compatible. e.g. if otest-shim targeted iOS 6.1 but a test bundle (or
# test host) targetted 5.0, you'd see errors.  We don't go older than 5.0 since
# we depend on some iOS 5+ APIs.
