# Generic makefile for any c realtime C plc 0, user servo or user phase
# For a new project change the following
# 
# 1.) usralgo-objs should be assigned the 'C' source code files that need to be compiled
# 2.) issue the command 'make depend' the first time a project is created and
#     (every time an additional 'C' file is added to the project the command 
#     'make depend' must be issued)
# 3.) issue the command make clean 
# 4.) issue the command make
#
# Notes
# --------
# Change DTDEBUG above to -O2 for release w/ optimization
# Change DTDEBUG above to -g3 for debug
