-# This script takes the directory full of the contents libc-partial*.a and

-# that aren't being wrapped in Libc. The usr-local-lib-system is the
-# /usr/local/lib/system or equivalent directory where the necessary symbol
-# files from Libc and Libsyscall reside.
-#
-# A Makefile is created that will build libc*.a from the contents of the
-# out-directory after symbol aliasing has been added.
-#
-# The out-directory path must be of the form ".../arch/form", where arch is
-# the architecture being built and form is one of debug, dynamic and profile.
