# quick, very dirty little script so that we can put all the
# information for building a residue book set (except the original
# partitioning) in one spec file.

#eg:

# >res0_128_128 interleaved
# haux 44c0_s/resaux_0.vqd res0_96_128aux 0,4,2 9
# :1 res0_128_128_1.vqd, 4, nonseq cull, 0 +- 1
# :2 res0_128_128_2.vqd, 4, nonseq, 0 +- 1(.7) 2
