#------------------------------------------------------------------------
#
# The behaviour of this Makefile is following:
#
# 1. 'make cleanAll' cleans all files that are produced by this
# Makefile.
#
# 2. in the clean directory, just typing 'make' builds the .dvi file
# with *correct* bibliographic references; it runs latex 3 times to
# fix the references and bibtex to produce the citation list for the
# article as appropriate.
#
# 3. Now, if you modify the source .tex file and say 'make', the latex
# will be run only once, which is much faster but can build some new
# references incorrectly. To run the full "3-latex procedure" again,
# either type 'make cleanAll; make' or touch the .bib file(s) and type
# make (or use make's -W option)
#
