Documentation for cws.x-2.0

The program cws.x creates the weight systems and combined weight systems ('cws') that are required for the classification of reflexive polytopes. The help screens are

cws.x -h
This is `cws.x': create weight systems and combined weight systems.
Usage:   cws.x -<options>;     the first option must be `w', `c', `i', or `h'.

Options: -h        print this information

         -w# [L H] make IP weight systems for #-dimensional polytopes.
                   For #>4 the lowest and highest degrees L<=H are required.
             -r/-t make reflexive/transversal weight systems (optional).

         -c#       make combined weight systems for #-dimensional polytopes.
                   For #<=4 all relevant combinations are made by default,
                   otherwise the following option is required:
             -n[#] followed by the names wf_1 ... wf_# of weight files
                   currently #=2,3 are implemented.
              [-t] followed by # numbers n_i specifies the CWS-type, i.e.
                   the numbers n_i of weights to be selected from wf_i.
                   Currently all cases with n_i<=2 are implemented.

          -i       compute the polytope data M:p v [F:f] N:p [v] for all IP
                   CWS, where p and v denote the numbers of lattice points
                   and vertices of a dual pair of IP polytopes; an entry  
                   F:f and no v for N indicates a non-reflexive `dual pair'.
              -f   use as filter; otherwise parameters denote I/O files

and

cws.x -x
This is `cws.x': -x gives undocumented extensions:
              -ip    printf PolyPointList
              -id    printf dual PolyPointList
              -N     make CWS for PPL in N lattice
              -p#    [infile1] [infile2] makes cartesian product
                     of Vertices. # dimensions are identified.
              -S     count simplex points for weight system
              -L     count using LattE (-> count redcheck cdd)

As these are very specialized applications there is perhaps no need for more detailed descriptions.

The C routines that are executed by cws.x with its various options can all be found in the file cws.c; there is no extra header file.
