# Examples Makefile
#
# Type "make" to generate examples.pdf containing many examples.
# Type "make clean; make examples.ps" to invoke latex intead of pdflatex.
# Type "make <diag>.ps" to make a postscript file from <diag>.m4
#  It may be necessary to type "make clean" before this or any of the following:
# Type "make <diag>.eps" to make an .eps file from <diag>.m4
# Type "make <diag>.svg" to make an .svg file from <diag>.m4 using pdf2svg
#   The following require ImageMagick convert:
# Type "make <diag>.png" to make a .png file from <diag>.m4
# Type "make <diag>.tif" to make a .tif file from <diag>.m4
#
#      See also: dpv subdirectory for creating svg with dpic -v without LaTeX
#
# To test the file test.m4, type "make tst" if boxdims is used, otherwise
# type "make tst1".  In either case the file tst.ps is created.
#
# There are more examples in the extras directory. Go to that
# directory and process them one at a time, or type "make".
#
# To debug a single diagram in a directory other than this examples
# directory, copy this makefile and tst.tex to where you want to work,
# redefine LIBDIR (below) appropriately, and type "make <diag>.xxx"
# where xxx is one of ps, eps, png, or pdf
