SYNOPSIS

9       copyg [-gszfp#:#qhx] [infile [outfile]]

DESCRIPTION

12              Copy a file of graphs with possible format conversion.
13
14       -g     Use graph6 format for output
15
16       -s     Use sparse6 format for output
17
18       -z     Use digraph6 format for output
19
20       -i     Use incremental sparse6 format for output
21
22              In  the  absence  of -g, -s, -z or -i, the format depends on the
23              header or, if none, the first input line.  As an exception,  di‐
24              graphs are always written in digraph6.
25
26       -p# -p#:#
27
28              Specify  range  of input lines (first is 1) This can fail if the
29              input has incremental lines.
30
31       -f     With -p, assume input lines of fixed length
32
33              (ignored if header or first line has sparse6 format).
34
35       -I#    Have at most this number of incremental steps
36
37       in a row.
38              Implies -i.
39
40       -h     Write a header.
41
42       -x     Don't write a header.
43
44              In the absence of -h and -x, a header is written if there is one
45              in the input.
46
47       -q     Suppress auxiliary output.
