From the developer:
OSX GCC Installer is an application that either allows you to install the essential compilers from pre-built binary packages or helps you create your own installer. To create your own package, you need to place the Xcode Installer for your OS version (Install Xcode.app) in the root directory of the repository, then open the matching .pmdoc.
You may want to check out more Mac applications, such as bitnami-sugarcrm--osx-x86-installer, Escale OSX or MPlayer OSX Extended, which might be related to OSX GCC Installer.
