NAME

       nef.x, nef-<num>d.x - compute Hodge numbers of nef-partitions

SYNOPSIS

       nef.x <Options>

DESCRIPTION

       The  nef-<num>d.x variant programs, where <num> is one of 4, 5, 6 and 11 work in different
       dimensions ; nef.x defaults to dimension 6.

   Options
       -h     prints this information

       -f or -
              use as filter; otherwise parameters denote I/O files

       -N     input is in N-lattice (default is M)

       -H     gives full list of Hodge numbers

       -Lv    prints L vector of Vertices (in N-lattice)

       -Lp    prints L vector of Points (in N-lattice)

       -p     prints only partitions, no Hodge numbers

       -D     calculates also direct products

       -P     calculates also projections

       -t     full time info

       -cCODIM
              codimension (default = 2)

       -Fcodim
              fibrations up to codim (default = 2)

       -y     prints poly/CWS in M lattice if it has nef-partitions

       -S     information about #points calculated in S-Poly

       -T     checks Serre-duality

       -s     don't remove symmetric nef-partitions

       -n     prints polytope only if it has nef-partitions

       -v     prints vertices and #points of input polytope in one line; with -u, -l  the  output
              is limited by #points:

       -uPOINTS
              ... upper limit of #points (default = POINT_Nmax)

       -lPOINTS
              ... lower limit of #points (default = 0)

       -m     starts with [d  w1 w2 ... wk d=d_1 d_2 (Minkowski sum)

       -R     prints vertices of input if not reflexive

       -V     prints vertices of N-lattice polytope

       -Q     only direct products (up to lattice Quotient)

       -gNUMBER
              prints points of Gorenstein polytope in N-lattice

       -dNUMBER
              prints points of Gorenstein polytope in M-lattice

       if NUMBER = 0 ... no
              0/1 info

       if NUMBER = 1 ... no redundant
              0/1 info (=default)

       if NUMBER = 2 ... full
              0/1 info

       -G     Gorenstein cone: input <-> support polytope
