#
# This file selects a PHP version, based on the user's preferences and
# the installed packages. It does not add a dependency on the PHP
# package.
#
# === User-settable variables ===
#
# PHP_VERSION_DEFAULT
# The PHP version to choose when more than one is acceptable to
# the package.
#
# Possible: 4 5
# Default: 5
#
# === Package-settable variables ===
#
# PHP_VERSIONS_ACCEPTED
# The PHP versions that are accepted by the package.
#
# Possible: 4 5
# Default: 4 5
#
# PHP_VERSION_REQD
# If the package works only with a specific PHP version, this
# variable can be used to force it.
#
# Possible: (undefined) 4 5
# Default: (undefined)
#
# === Variables defined by this file ===
#
# PKG_PHP_VERSION
# The selected PHP version.
#
# Possible: 4 5
# Default: ${PHP_VERSION_DEFAULT}
#
# PKG_PHP
# The same as ${PKG_PHP_VERSION}, prefixed with "PHP".
# XXX: Why is this necessary?
#
# PHPPKGSRCDIR
# The directory of the PHP implementation, relative to the
# package directory.
#
# Example: ../../lang/php5
#
# PHP_PKG_PREFIX
# The prefix that is prepended to the package name.
#
# Example: php5
#
# Keywords: php
