planarg(1)
NAME
planarg - For each input, write to output if planar.
SYNOPSIS
planarg [-v] [-nVq] [-p|-u] [infile [outfile]]
DESCRIPTION
For each input, write to output if planar.
- The output file has a header if and only if the input file does.
- -v Write non-planar graphs instead of planar graphs
- -V Write report on every input
- -u Don't write anything, just count
- -p Write in planar_code if planar (without -p, same format as
- input)
- -k Follow each non-planar output with an obstruction in sparse6
- format (implies -v, incompatible with -p)
- -n Suppress checking of the result
- -q Suppress auxiliary information
This program permits multiple edges and loops
