# doit - make all or some example picture sets.

# Usage: doit      # make them all
#        doit nnx  # make nnx.pdf and snnx.pdf
#
# pictures are numbered 01, 02, etc.
# nn[a-z] has code to typeset a \ctable; for nn[k-z] page layout will be shown
# for each nn[a-z] two pdfs are generated:
#      nn[a-z].pdf for the ctable picture
# and snn[a-z].pdf for the source code verbatim.
# The prefix (s) for source verbatims and (empty) for result files is set by PRE
