the -f (freq scrunch) and -t (time scrunch) options used to be the same as the pam -f -t options, and scrunch the number of times specified. Now they scrunch to the given number of sub-ints/bands. Either the help page needs to be updated to the new functionality, or the old functionality needs to be restored.
This has been open for 4 years and still not fixed. Awesome.
Fixed in db17d92
Functionality of -f and -t now like in pam.
