# Makefile for PFP-Journal paper.
# This is a generic Makefile for running LaTeX.
# You should only have to set the name of the .ps file you want to produce.
#
# Make targets:
#  all      ... build the entire paper
#  show     ... buidl and show the paper via ghostview
#  chk-cvs  ... check CVS status of all .tex files 
#  count    ... count the number of words in all .tex files
#  update   ... do a CVS update
#  prgs     ... type-set all programs in discussion/ (not in src/)
#  clean    ... delete all intermediate files used by LaTeX
#
# Structure of this directory:
#  ./ contains the top-level and general .tex files
#  discussion/ contains tex files discussing individual programs (1 dir per prg)
#  results/ contains the results for all prgs
#  src/ contains the prg code for all prgs as used for the measurements
#  bin/ contains aux tools used for the paper (measurement, pretty printing)
