# ##################################
# Mainly of interest for Objective-C
# ##################################
# Libraries are built in two stages:
#
# In the first step the PROJECT_FILES are compiled.
# In the second step STAGE2_SOURCES are added.
# This allows PostLibrary to run an analysis step over PROJECT_FILES and
# generate files to be included by STAGE2_SOURCES. If there are no
# STAGE2_SOURCES then this is just a more verbose way of doing it.
# OBJC_LOADER_INC is the generated analysis step.
