PCL stands for Portable Class Library - http://msdn.microsoft.com/en-us/library/gg597391.aspx
This branch will further work on lucene.net for moving the project towards supporting portable libraries. The goal is to bring Lucene.Net to other .NET Platforms.
Since this will require significant work, it will be done in its own branch "pcl" in parallel to other efforts. The PCL branch can pull from other branches as needed as well as provide enhancements to the master branch as they are stable.
