# @BLURB: Functions to allow ebuilds to depend on php5 and check for specific features.

# @DESCRIPTION:
|
|
# This eclass provides functions that allow ebuilds to depend on php5 and check

# for specific PHP features, SAPIs etc. Also provides dodoc-php wrapper to install
|
|
# documentation for PHP packages to php-specific location.
|
|
# This eclass is deprecated and is set to be removed 30 days after bug 552836 is resolved

|
|
#
|
|
# local flags="pcre session snmp sockets wddx"

# use mysql && flags="${flags} mysql"

# use postgres && flags="${flags} postgres"
