# N.B. All the artwork is generated from sketch files so you need the
# sketch package installed.  In particular the sk2ps command should be
# installed as part of that package.  sk2ps is used to convert sketch 
# files to eps (encapsulated postscript) files.

SK2PS = sk2ps

# N.B. need ps2eps from
# http://www.telematik.informatik.uni-karlsruhe.de/~bless/ps2eps.html to
# convert from one-paged postscript (ps) to encapsulated postscript (eps).
# You need both ps2eps and bbox (from the package) in your path.  The first 
# is a perl script and the second a small compiled executable required by 
# the script.

# The much better known ps2epsi frankly sucks at this (just bombed out when
# I tried it) for these purposes so use ps2eps instead!

# convert (from ImageMagick) also does a fair job of converting from one-page
# ps to eps, but it only copies scalable vector drawing stuff with no font 
# or letter metadata (helpful when doing antialised rendering).

# N.B need epstopdf (from tetex-bin) to convert from eps to pdf since that
# programme seems to do a better job than convert (which bitmaps!) for the
# particular cases here.  Also note, however, that even epstopdf loses the
# font and character information (although it retains the vectorized
# representation) so the results look bad (no anti-aliasing) when they
# include characters.
