# 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 for figures. 
# PDF form is required for quagga.pdf, using PDFTex at least.
#
# TeX implementation, which we depend on already anyway.
