This is `cws.x': create weight systems and combined weight systems.
Usage: cws.x -; the first option must be -w, -c, -i, -d or -h.
Options: -h print this information
-f use as filter; otherwise parameters denote I/O files
-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'.
-d# compute basic IP weight systems for #-dimensional
reflexive Gorenstein cones;
-r# specifies the index as #/2.
-2 adjoin a weight of 1/2 to the input weight system.
-N make CWS for PPL in N lattice.
