Everything not being a valid option will be interpreted as a potential datafile name. Given no datafile at all, means read stdin. Also - means stdin
Possible options are:
| Option | Description | Default |
|---|---|---|
| -l# | number of data to use | whole file |
| -x# | number of lines to be ignored | 0 |
| -c# | column to be read | 1 |
| -i# | number of iterations | 1 |
| -V# | verbosity level (0: only save the last iteration otherwise: save all iterations) | otherwise |
| -o# | output file name | 'datafile'.low.n, where n is the iteration (or stdin.low.n if stdin was read) without -o the last iteration is also written to stdout |
| -V# | verbosity level 0: only panic messages 1: add input/output messages 2: print each iteration to a separate file | 1 |
| -h | show these options | none |
