Mer/Build
This section documents how to use the openSUSE Build Service with Mer. More on the openSUSE Buildservice here.
A simple way to think of OBS is as a version control system for source tarballs and .dsc files and whenever you commit a tarball the build farm compiles it for you.
Over and above this OBS provides a local tool called osc that lets you do clean builds not only for your own OS and architecture but also for other distros and even other architectures (armel).
Getting Started
The first thing to do is to install OBS. This will provide access to the tools and source used to build Mer.
Then you should become familiar with building an application using OBS but outside the Mer repository. This is explained in detail in Application Building.
When you are comfortable with that it makes sense to look at the Mer Packages.
Finally there are processes used to manage the Mer packages.
