Homebrew (http://brew.sh/) is the package manager for macOS. This is the Homebrew tap for GAP, which will install the latest official GAP release and will attempt to build as many GAP packages as possible.
To perform GAP Homebrew installation for the first time, call
brew install gap-system/gap/gap
To upgrade an existing GAP Homebrew installation, call
brew upgrade gap-system/gap/gap
To test the GAP Homebrew installation, call
brew test gap-system/gap/gap
For the test with a more verbose output, start GAP and then call
Read( Filename( DirectoriesLibrary("tst"), "testinstall.g" ));

The initial formula for GAP has been provided by Alexey Muranov
and has been migrated to this repository after the deprecation of
homebrew-science (https://github.com/Homebrew/homebrew-science).
