# SwiftGit2
#
# Executes the build and runs tests for Mac and iOS. Designed to be invoked by
# Travis as a matrix build so that the two platform builds can run in parallel.
#
# Dependent tools & scripts:
# - script/bootstrap
# - script/update_libssl_ios
# - [xcodebuild](https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/xcodebuild.1.html)
# - xcpretty (gem)
# - xcpretty-travis-formatter (gem)
#
# Environment Variables:
# - SCHEME: specifies which Xcode scheme to build. Set to one of the following:
#   - SwiftGit2-OSX
#   - SwiftGit2-iOS
# - TRAVIS: indicates when the build is being run by travis, used to invoke
#           the xcpretty-travis-formatter gem for output.
