Source: php5-$EXTENSION
Section: php
Priority: optional
Maintainer: $MAINT_GECOS
Build-Depends: debhelper, php5-dev
Standards-Version: 3.9.1

Package: php5-$EXTENSION
Architecture: any
Depends: \${shlibs:Depends}, \${misc:Depends}, \${php:Depends}, php5-common (= $PHPVERSION)
Description: $EXTENSION module for php5
 This package provides a module for $EXTENSION functions in PHP scripts.
 .
 PHP5 is a widely-used general-purpose scripting language that is
 especially suited for Web development and can be embedded into HTML.
 The goal of the language is to allow web developers to write
 dynamically generated pages quickly. This version of PHP5 was built
 with the Suhosin patch.
