# Precapsim shell script
#
# written by Sasan H. Ardalan
# June 6, 1989.
#
# usage: precapsim flag block1 block2 block3 ...
# where flag is one of the following:
#
#  no flag: blockGen and compile each block and add to library. 
#	    Create custom capsim with blocks included.
#  -s:	    blockGen and compile only.
#  -a: 	    add block object file  to library and create custom capsim
#  -l:	    link only. Creates custom capsim.
#  -d:	    delete the blocks.
#  -dl:	    delete the blocks and create custom capsim
#
# Note: blocks should not have suffix. Example,
# 	precapsim -s add mixer filter
