# Makefile that defines how we build 'procedures', which are a special kind of
# module recognized by Cronus.
# BUILD_PROCEDURE
# This macro will automatically generate all the recipes for building a
# procedure. Requires that the following variables are defined prior to
# calling this macro:
# * PROCEDURE=name - Name of the procedure. name.o is an implied
# required object.
# * FAPI=version - Optional method to specify the FAPI version.
#
# Input: $1
# * Optional input to delay the running of BUILD_MODULE macro to a
# later phase
#
