# Description
# -----------
# This Makefile is used to build the libcrc library. The only action you should
# normally have to do is to run the make program from the command line,
# independent on the Operating System you are working on.
#
# This Makefile is manually maintained. No autoconf or automake involved. This
# was a deliberate decision due to the absense of these tools on some systems,
# in particular in Windows environments.
#
# Dependencies
# ------------
# This Makefile is known to be functional with GNU Make. Other make utilities
# may work or may have problems. GNU Make is available both in source code
# and precompiled binaries for a large number of environments and therefore
# you are recommended to install a version of GNU Make if you encounter
# problems with the default make utility in your development chain.
#
# Aside from GNU Make and the standard C compiler headers and libraries which
# should have been installed already together with your compiler there are no
# other known dependencies.
#
# Library Type
# ------------
# The generated library is a library useable for static linking in this
# source directory structure. The decision for a static linkable library
# was deliberate because of the relatively small size of the library and the
# routines and to avoid version and dependency issues when distributing the
# end application to different environments.
