# @MAINTAINER:
# Gentoo PHP team <php-bugs@gentoo.org>
# @BLURB: A unified interface for adding standalone PHP extensions.
# @DESCRIPTION:
# This eclass provides a unified interface for adding standalone
# PHP extensions (modules) to the php.ini files on your system.
#
# Combined with php-ext-source-r1, we have a standardised solution for supporting
# PHP extensions.

# @DESCRIPTION:
# The extension name. This must be set, otherwise the eclass dies.
# Only automagically set by php-ext-pecl-r1.eclass, so unless your ebuild
# inherits that eclass, you must set this manually before inherit.
