In botany (the science of plants), Pyrus is the genus of the pear family, and thus includes all of the pear-producing trees and shrubs under its taxonomical umbrella.

In PHP (the hypertext programming language), Pyrus is the next-generation PEAR Installer, a revolutionary package management and distribution system that extends the functionality of the PEAR Installer's already advanced functionality. Pyrus is also friendlier to projects outside of PEAR that wish to take advantage of the strengths of PEAR through channels.

Pyrus represents the cumulative effort of years of work, experience with the PEAR Installer since its inception in 1999, and feedback from users like you. We are very proud to present the best installation tool for PHP.
