+# - script/bootstrap
+# - script/update_libssl_ios
+# - [xcodebuild](https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/xcodebuild.1.html)

+#
+# Environment Variables:
+# - SCHEME: specifies which Xcode scheme to build. Set to one of the following:
+#   - ObjectiveGit Mac
+#   - ObjectiveGit iOS
+# - TRAVIS: indicates when the build is being run by travis, used to invoke
+#           the xcpretty-travis-formatter gem for output.
