2# Makefile for the automation of LaTeX document processing
3#
4# Usage: make [target]
5# The following targets are understood:
6# dvi generate dvi output (latex default target)
7# pdf generate pdf output (pdflatex default target)
8# ps generate postscript
9# clean erase all intermediate files
10# realclean erase all but the source files
11#
12# To do:
13# -recursively process \include{} and \input{} commands for .tex
14# dependancies
15# -do the same for \bibliography{} commands
16# -add metapost processing
17#
18
19#
20# Document information (provided by top-level Makefile)
21#
22# LATEX
23# The name of the latex compiler to use. If the program name is,
24# specifically, "pdflatex" then the .pdf will be the default target
25# rather than the .dvi. Note that at present there is no way to ask
26# for one or the other without switching the contents of this
27# variable.
28#
29# DOCUMENT
30# (required) The root name for all files.
31#
32# GRAPHIC_FILES
33# Any graphic files the document depends on, for example any .eps or
34# .pdf files included with \includegraphics{}. The output is rebuilt
35# if any of these files change but otherwise they play no role in the
36# build process.
37#
38# XFIG_FILES
39# Thes Makefile rules allow your LaTeX document to include xfig .fig
40# files directly. Each .fig file is converted to a graphic format
41# suitable for inclusion by the LaTeX processor, for example
42# postscript or pdf. This is accomplished by processing the .fig
43# file with fig2dev and producing two output files: a graphics
44# version of the .fig file and a LaTeX source file containing the
45# commands needed to import that graphics file. In your own LaTeX
46# document, you will need to include this .tex source file. For
47# example, if you have an xfig file called diagram.fig, you should
48# set "XFIG_FILES = diagram.fig" in your Makefile and place the
49# command "\include{diagram.fig}" in your LaTeX document where you
50# would like the image placed. When your document is processed, the
51# xfig file will be converted to a, for example, postscript file
52# called diagram.fig.ps and a LaTeX source file called
53# diagram.fig.tex. The \include{} command in your LaTeX source reads
54# in the .fig.tex file (the .tex extension is assumed by the command)
55# which in turn contains the commands to import the graphics file.
56#
57# As an added bonus, any text objects in the xfig document that have
58# their "special" flag set will be removed from the document before
59# it is converted to a graphics format. Their contents are added to
60# the LaTeX source file along with the commands needed to overlay
61# them in the correct places on the figure. In this way, you can use
62# LaTeX to typset the text of your xfig figure. This has the
63# advantage of having the text rendered in the same font as the rest
64# of your document and also allows you to make use of all of LaTeX's
65# typsetting facilities. Note that in your xfig document you should
66# set the pen colour of the "special" text to "Default" in order to
67# prevent \color commands from being issued, otherwise you will need
68# to include the LaTeX package "color".
69#
70# If you get error messages about "unknown graphics format" related
71# to the .fig.ps or .fig.pdf intermediate graphics file then you must
72# issue the \DeclareGraphicsRule{.fig.ps}{eps}{.fig.ps}{} command or
73# the \DeclareGraphicsRule{.fig.pdf}{pdf}{.fig.pdf}{} command in your
74# document's preamble. See the grfguide.ps graphics package
75# documentation for more information.
76#
77# BIB_FILES
78# $(DOCUMENT).tex will be automatically searched for all .bib files
79# specified via \bibliography{} commands. Use this variable to
80# override the automatic search and manually specify the .bib files.
81# Reasons for wanting to override the automatics: (i) scanning a
82# large document can be time-consuming and can be skipped by entering
83# the info yourself (ii) the algorithm may be broken for your
84# document.
85#
86# BSTINPUTS
87# BIBINPUTS
88# The contents of these variables override the system default search
89# paths for bibtex. If you are using a custom bibliographic style,
90# you may need to set BSTINPUTS to the directory in which the .bst
91# file resides. If your .bib databases cannot be found, then you
92# will need to set BIBINPUTS to a colon-separated list of the
93# directories in which they reside.
94#
95# DVIPS_FLAGS
96# Flags to pass to dvips. It might be necessary to include the -K
97# flag if you are having trouble getting mpage to handle documents
98# that contain EPS figures generated by certain applications.
