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 |
| -p# | number of poles | 128 |
| -f# | number of frequences to print | number of poles |
| -o# | output file name | without file name: 'datafile'.spec (or stdin.spec if data were read from stdin) Without -o data is written to stdout |
| -V# | verbosity level 0: only panic messages 1: add input/output messages 2: add the AR coefficients to the output | 1 |
| -h | show these options | none |
