nef-4d.x: Compute hodge numbers of nef-partitions

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.

-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
