Ebuild
|
|
An Ebuild is a bash script written for the Portage system of Gentoo Linux. Each application in the portage tree has an ebuild written for it, and the ebuild, invoked with "emerge nameofebuild", automatically compiles (if necessary) and installs the program, and any required dependencies. Ebuild files are usually named as "name-version.ebuild". Usually, the ebuild is designed to install an application from source, although some ebuilds are designed for binaries. Other ebuilds install meta-packages or virtual packages. Here is an example ebuild for the Beep (http://www.johnath.com/beep/) software:
