## Process this file with automake to produce Makefile.in.

# Dia, the version i have at least, doesn't do very good EPS output
# (some of the text is scaled strangely). So this will work, but 
# it is probably better to use something like gimp to convert the 
# dia exported PNG files to EPS manually.
#
# Here we use 'convert' from the well known 'ImageMagick' package
# to do conversion from png to eps.
#
# PDF is required for quagga.pdf, we use epstopdf from the well known TeTeX
# TeX implementation, which we depend on already anyway.
#
# dia -> (dia) -> png -> (convert) -> eps -> (epstopdf) -> pdf
DIATOPNG = dia -t png -e
DIATOEPS = dia -t eps -e
PNGTOEPS = convert

# rather twisted logic because we have to build PDFs of the EPS figures for
# PDFTex and yet build one PDF, quagga.pdf, from texi source. Which means we
# cant rely on a single automatic rule for *.pdf, eg the one automatically
# provided by automake. If you are an automake wizard, please feel free to
# compact it somehow.
