# make the dependencies
# Make knows that a .cpp relies on the header that yacc generates, so it runs
# yacc before generating the dependency lists and including them.
#
# This is essentially the example included in the Gnu Make documentation (see
# Generating Prerequisites Automatically) except that in this case the .o's are
# not in the same directory as the .cpp's, hence the substitution in the sed
# command.
#
# The leading @ tells Make to silently execute the command
# set -e tells the shell (Bash specific?) to exit at the first error
# The $$$$ translate the the shell variable $$, which translates to the
# current pid.  For this reason, all of the trailing \'s are required to
# ensure that all the commands execute under the same shell invocation.
#
# Finally, the "-include" command includes the files that were just made, but
# not if the goal is to clean the directories.
