# Makefile for generating LaTeX documents
# -----------------------------------------------------------------------
#
# This is a simple makefile for generating LaTeX documents. It will
# run bibtex, generate eps from xfig figures, and make pdfs. The
# makefile supports builds in non-source directories: just make a
# build directory, copy the makefile there, and change the srcdir
# variable accordingly.
#
# Note that the makefile assumes that the default dvips/ps2pdfwr 
# commands "do the right thing" for fonts in pdfs. This is true on 
# Athena/Linux and Fedora Core but is not true for older redhat installs ...
#
# At a minimum you should just change the main variable to be
# the basename of your toplevel tex file. If you use a bibliography 
# then you should set the bibfile variable to be the name of your
# .bib file (assumed to be in the source directory).
#

# Targets:
#  (none)	makes PDFs in output/
#  clean	removed everything except PDFs in output/
#  clean-all	removed everything in output/

# Directories relative to the top level:
outdir    = output
srcdir    = src
# Relative to output:
relsrcdir = ../$(srcdir)
