# The following function should be added to eutils.eclass (see bug #143572):

# Generate an standard error message for missing USE flags
# in existing packages, and die.
#
# Usage: built_with_use_error <category/package> <functionality> [<USE flag>]
#    ex: built_with_use_error dev-util/subversion python
#    or: built_with_use_error net-www/apache LDAP ldap
#
# Typical usage:
#	if ! built_with_use dev-util/subversion python ; then
#        built_with_use_error dev-util/subversion python
#   fi
#
# Note: when <USE flag> is not specified, <functionality> is used for the USE flag name.
