In late 2005, Computing & Communications at the University of Washington began 
a project to create a new family of email tools built upon the PineŽ Message 
System. This family of tools is called Alpine. Alpine consists of a UNIX 
command-line program, a PC version, and a Web version.

Alpine will be licensed under the Apache License, Version 2.0.

Why Alpine? The Pine Team wanted to reorganize the very mature Pine source 
code, distribute the Web version that has been very popular here at the 
Univerity of Washington, and relax our trademark obligation for source code 
quality control to a world-wide customer base.

The trademark obligation represents an ongoing administrative effort. 
Coincidentally, the UW is standardizing its license for the several other 
products we offer to the Apache License, Version 2.0.

The cleanest way to do all this was to stop developing Pine (a registered 
trademark) and start a new product - thus Alpine was born.
