eh_sgl

USAGE: eh_sgl infile [-v] [-d] [-s] [-a] [-l] [-b] [-h] [-q]
[-n n] [-i f] [-f f] [-w] [-L]

eh_sgl extracts histogram data from SGL output files created by xsgll

ARGUMENTS:
infile: input filename (SGL)

OPTIONS:
-v: expect vertex coordinates in .sgl file
-d: disply input data

construct histogram for:
    -s: segment number (per SGL)
    -a: area
    -l: length
    -b: width
    -h: (convex) hull area
    -q: quotient area/conv hull area

-n n: set number of bins to n (default: 10)
-i f: set initial value to f(float)
-f f: set final value to f(float)
-w: write output file of type .hdt (hist data)
-L: print Software License for this module
