#
# Makefile for the automation of LaTeX document processing
#
# Usage: make [target]
# The following targets are understood:
# dvi generate dvi output (latex default target)
# pdf generate pdf output (pdflatex default target)
# ps generate postscript
# clean erase all intermediate files
# realclean erase all but the source files
#
# To do:
# -recursively process \include{} and \input{} commands for .tex
# dependancies
# -do the same for \bibliography{} commands
# -add metapost processing
#
#
# Document information (provided by top-level Makefile)
#
# LATEX
# The name of the latex compiler to use. If the program name is,
# specifically, "pdflatex" then the .pdf will be the default target
# rather than the .dvi. Note that at present there is no way to ask
# for one or the other without switching the contents of this
# variable.
#
# DOCUMENT
# (required) The root name for all files.
#
# GRAPHIC_FILES
# Any graphic files the document depends on, for example any .eps or
# .pdf files included with \includegraphics{}. The output is rebuilt
# if any of these files change but otherwise they play no role in the
# build process.
#
# XFIG_FILES
# Thes Makefile rules allow your LaTeX document to include xfig .fig
# files directly. Each .fig file is converted to a graphic format
# suitable for inclusion by the LaTeX processor, for example
# postscript or pdf. This is accomplished by processing the .fig
# file with fig2dev and producing two output files: a graphics
# version of the .fig file and a LaTeX source file containing the
# commands needed to import that graphics file. In your own LaTeX
# document, you will need to include this .tex source file. For
# example, if you have an xfig file called diagram.fig, you should
# set "XFIG_FILES = diagram.fig" in your Makefile and place the
# command "\include{diagram.fig}" in your LaTeX document where you
# would like the image placed. When your document is processed, the
# xfig file will be converted to a, for example, postscript file
# called diagram.fig.ps and a LaTeX source file called
# diagram.fig.tex. The \include{} command in your LaTeX source reads
# in the .fig.tex file (the .tex extension is assumed by the command)
# which in turn contains the commands to import the graphics file.
#
# As an added bonus, any text objects in the xfig document that have
# their "special" flag set will be removed from the document before
# it is converted to a graphics format. Their contents are added to
# the LaTeX source file along with the commands needed to overlay
# them in the correct places on the figure. In this way, you can use
# LaTeX to typset the text of your xfig figure. This has the
# advantage of having the text rendered in the same font as the rest
# of your document and also allows you to make use of all of LaTeX's
# typsetting facilities. Note that in your xfig document you should
# set the pen colour of the "special" text to "Default" in order to
# prevent \color commands from being issued, otherwise you will need
# to include the LaTeX package "color".
#
# If you get error messages about "unknown graphics format" related
# to the .fig.ps or .fig.pdf intermediate graphics file then you must
# issue the \DeclareGraphicsRule{.fig.ps}{eps}{.fig.ps}{} command or
# the \DeclareGraphicsRule{.fig.pdf}{pdf}{.fig.pdf}{} command in your
# document's preamble. See the grfguide.ps graphics package
# documentation for more information.
#
# BIB_FILES
# $(DOCUMENT).tex will be automatically searched for all .bib files
# specified via \bibliography{} commands. Use this variable to
# override the automatic search and manually specify the .bib files.
# Reasons for wanting to override the automatics: (i) scanning a
# large document can be time-consuming and can be skipped by entering
# the info yourself (ii) the algorithm may be broken for your
# document.
#
# BSTINPUTS
# BIBINPUTS
# The contents of these variables override the system default search
# paths for bibtex. If you are using a custom bibliographic style,
# you may need to set BSTINPUTS to the directory in which the .bst
# file resides. If your .bib databases cannot be found, then you
# will need to set BIBINPUTS to a colon-separated list of the
# directories in which they reside.
#
# DVIPS_FLAGS
# Flags to pass to dvips. It might be necessary to include the -K
# flag if you are having trouble getting mpage to handle documents
# that contain EPS figures generated by certain applications.
