# generic rule for using ps4pdf
# The idea is to run ps4pdf once and if the file contains some bibliography,
# run bibtex and recompile. If labels get changed etc., a third run is issued.
# The second and third runs are pdflatex only, because otherwise the .aux file
# gets re-created and forgets label positions.
