-# @FUNCTION: built_with_use
-# @USAGE: [--hidden] [--missing <action>] [-a|-o] <DEPEND ATOM> <List of USE flags>
-# @DESCRIPTION:
-#
-# Deprecated: Use EAPI 2 use deps in DEPEND|RDEPEND and with has_version calls.
-#
-# A temporary hack until portage properly supports DEPENDing on USE
-# flags being enabled in packages.  This will check to see if the specified
-# DEPEND atom was built with the specified list of USE flags.  The
-# --missing option controls the behavior if called on a package that does
-# not actually support the defined USE flags (aka listed in IUSE).
-# The default is to abort (call die).  The -a and -o flags control
-# the requirements of the USE flags.  They correspond to "and" and "or"
-# logic.  So the -a flag means all listed USE flags must be enabled
-# while the -o flag means at least one of the listed IUSE flags must be
-# enabled.  The --hidden option is really for internal use only as it
-# means the USE flag we're checking is hidden expanded, so it won't be found
-# in IUSE like normal USE flags.
-#
-# Remember that this function isn't terribly intelligent so order of optional
-# flags matter.
