This is  `class.x', a program for classifying reflexive polytopes
Usage:     class.x  [options] [ascii-input-file [ascii-output-file]]
Options:   -h          print this information
           -f or -     use as filter; otherwise parameters denote I/O files
           -m*         various types of minimality checks (* ... lvra)
           -p* NAME    specification of a binary I/O file (* ... ioas)
           -d* NAME    specification of a binary I/O database (DB) (* ... ios)
           -r          recover: file=po-file.aux, use same pi-file
           -o[#]       original lattice [omit up to # points] only
           -s*         subpolytopes on various sublattices (* ... vphm)
           -k          keep some of the vertices
           -c          check consistency of binary file or DB
           -M[M]       print missing mirrors to ascii-output
           -a[2b]      create binary file from ascii-input
           -b[2a]      ascii-output from binary file or DB
           -H*         applications related to Hodge number DBs (* ...cstfe)

Type one of [m,p,d,r,o,s,c,M,a,b,H] for help on options,
`g' for general help, `I' for general information on I/O or `e' to exit:
