# A LaTeX/MetaPost makefile -- requires GNU Make

# John D. Ramsdell -- The MITRE Corporation

# The makefile assumes all the *.tex and *.mp source files in this
# directory are used to build one document.  You need not have any
# MetaPost source files to use this makefile.

# To use this file, include this file in your Makefile, and define
# BASE_NAME to be the base name of the document to be created.  If you
# use BiBTeX, define BIB_NAME to be the base name of the BiBTeX file.
# Define MP_MACROS to be the name of local MetaPost macro library
# files.

# Example Makefile:

# BASE_NAME = mydoc
# BIB_NAME = mybib
# include ltxmp.mk

# During development, this makefile doesn't always run enough programs
# in response to changes in the source files.  Be sure to precede a
# make with a make clean when you want to build a final version of a
# document.
