NAME

serate - Sudoku Explainer command line rating

SYNOPSIS

serate [ --diamond ] [ --format=FORMAT ] [ --input=FILE ] [ --output=FILE ] [ --pearl ] [ puzzle ... ]

DESCRIPTION

serate is a Sudoku Explainer command line entry point that rates one or more

input puzzles. If an --input=FILE option is specified then 81-character puzzle

strings are read from that file, otherwise if 81-character puzzle operands are

not specified the puzzles are read from the standard input. If an --output=FILE

option is specified then the output is written to that file, otherwise output

is written to the standard output. The output is controlled by the

--format=FORMAT option.

Ratings are floating point numbers in the range 0.0 - 20.0, rounded to the

tenths digit. 0.0 indicates a processing error and 20.0 indicates an valid

but otherwise unsolvable input puzzle.
