# This Makefile fragment is included by bsd.pkg.mk and provides all
# variables and targets related to the parallel bulk build
# tree-scanning code.
#
# The following are the "public" targets provided by this module:
#
# pbulk-index
# pbulk-index-item
#
# _PBULK_MULTI lists the multi-package variable.
# For each class the following variables are provided:
# _PBULK_MULTI_LIST.foo enumerates the supported settings
# _PBULK_MULTI_VAR.foo forces a specific version
# _PBULK_MULTI_DEFAULT.foo contains the default value
_PBULK_MULTI?= apache php python
