# - A file to be included to enable make(1) to process LaTeX files.
# Suitable for single-part documents with BibTeX references and diagrams.

#
# Note on commands:
# 'make doc1.dvi' - creates dvi file if make thinks that something has changed.
# 'make doc1' - also creates dvi file, unconditionally (useful if you havent
#		specified _all_ the things it depends on)
#
# Refer to man entry for make(1) for explanation of syntax and command options

# ---- The following shows the type of entries required in each Makefile ----

# include $(HOME)/lib/make_latex
# # Name(s) of LaTeX document file(s) (without suffixes)
# # eg.
# FILES = doc1 doc2
#
# # List here dependencies of documents on other files (eg diagrams 
# # from .gnu files) eg.
# doc1.dvi : fig1.ps fig2.ps fig3.ps
# doc2.dvi : diag1.ps diag2.ps
#
# # Names of additional files to be deleted by TIDY and CLEAN commands
# TIDYFILES = x
# CLEANFILES = y

# --------------- The following defaults may be user-configured --------------

# Default name(s) of BibTeX source files, eg.
BIBFILES = $(HOME)/Refs/myrefs.bib

# default printer resolution
