Pirum, the simple PEAR Channel Server Manager
Warning: Pirum is not maintained anymore, use Composer instead.
Pirum is a simple and nice looking PEAR channel server manager that lets you setup PEAR channel servers in a matter of minutes. Pirum is best suited when you want to create small PEAR channels for a few packages written by a few developers.
Pirum consists of just one file: a command line tool written in PHP. There are no external dependencies, no need for a database, and nothing needs to be installed or configured.
As of Pirum 1.1, a composer repository is generated as well.
