# OVERVIEW

# GNU Archiver Veneer
#
# DESCRIPTION
#
# This script wraps normal archive commands that're transparently
# passed-through. It adds value too, by addressing difficulties
# that would normally cause a developer to need `make clean`.
#
# EXAMPLE
#
# build/archive ar rcsD library.a foo.o ...
