Creating a "DMG installer" for OS X

A DMG Installer is convenient way to provide end-users a simple way to install an application bundle. They are basically a folder with a shortcut to the Applications directory but they can be customized with icons, backgrounds, and layout properties. A DMG file (.dmg) is a Mac OS X Disk Image file and it is used to package files or folders providing compression, encryption, and read-only to the package.

Инструментов мало. Тема сообществом мало проработана. Возможно, makefile всех устраивает.

Первая группа: замена утилиты make:

• makex понимает уже существующие makefiles.

Go, multiple packages and coveralls.io

Single profile for single Go package

For Go projects that consist of only one package, the following Travis configuration is enough to get started with coveralls.io. You may want to encrypt your $COVERALLS_TOKEN via Travis encryption keys though.

language: go
go:
 - 1.3.1
