##---------------------------------------------------------------------------
## 01.Dec,1996	forman	 Initial Makefile 
## 01.Jun,1997	forman	 Added support for print, preview, and bibtex
## 01.Jan,1998	stones	 tmp and lib directories to reduce clutter
## 05.Feb,1998	forman	 Added the following functions:
##			 .PHONY to prevent errors
##			 generic TEXFILE definition with following patsubst's
##			 vpath definitions
##			 gzip, gunzip, tar, ci
##			 search for \bibliography in tex file
##			 conditional ifeq omits bibtex if unnecessary
##			 documentation added
## 30.Nov,1998	forman	 Added TOPFILE and SECFILE definitions to support
##        		 texfiles with "input" commands.
## 23.Dec,1998	marshats Added RCSFILES and ci/co capabilites for multiple files
##                       Now only runs makeindex if $(IDX) file exists.
## 15.Mar,1999	forman	 Added 'make wc' for papers with word quotas.
## 24.Aug,1999	forman	 Converted Makefile to use pdftex as the primary
##			 complier.  Now generates true pdf and ps files.
## 09.Feb,2000	forman	 Simplified the documentation.  Removed direct
##			 compilation of tex into DVI and PS.  Conversion
##			 is done with PDF2PS now.
## 08.Aug,2000	forman	 Added define for figures directories.
## 18.Aug,2000	forman	 Removed the redundant code in the $(pdflatex) and
##			 $(pdflatex-bibtex) definitions by splitting them up
##			 into several smaller definitions which are called
##			 from a single set of "if-then" statements.
## 18.Aug,2000	forman	 Added support for glosstex and makeindex.
## 19.Aug,2000	forman	 To save space, all files in tmp are now links.
## 19.Aug,2000	forman	 Removed all postscript commands in favor of pdf.
##---------------------------------------------------------------------------
##
## This Makefile expects the following directory structure:
##
##     	Makefile	This file
##     	*.tex		Put latex files in root directory.
##     	RCS/		Create an RCS directory for "ci" and "co".
##	doc/		Document directory.  Includes gpl.txt.
##     	lib/		Put all cls, sty, idx, gdf, and bib files in lib.
##     	figures/	Put all figures in the figures directory.
##     	tmp/		Never put anything in tmp -- it gets cleaned out.
##
##---------------------------------------------------------------------------
##
## Normal Usage:
##	make 		Run pdflatex
##	make clean 	Remove all files in tmp and the pdf link in root.
##	make preview 	Preview the compiled file
##	make ci 	Check in the RCSFILES
##	make co 	Check out the RCSFILES
##
## Advanced Usage:
##	make gzip	Recursively gzip all the files in the root directory
##	make gunzip	Reverse the above process
##	make tar 	Tar and gzip the working directory
##	make wc		Count the number of words in your report
##
##---------------------------------------------------------------------------
## WARNING:
## 	If "make ci" fails, "make co" will nuke your files!
## 	Don't put anything in tmp, "make clean" will delete everything!
