I am pleased to announce the release of crunch 2.3. Crunch 2.3 has the following fixes/enhancements

Code:
version 2.1 permute now supports -b
              add signal handling - pressing ctrl break will cause crunch
              to finish the word it is processing and then gracefully exit instead of
              leaving files open and words half finished.  This is the first step in
              supporting resume.
              chunk now supports resume

version 2.2 pattern supports numbers and symbols

version 2.3 fix bytecount
              add new options to help screen
If you have any problems please let me know.
