rephrase - 0.2-4 main

If you can nearly remember your GnuPG passphrase - but not quite - then
Rephrase may be able to help. Tell Rephrase the parts of the passphrase you
know, and any number of alternatives for the parts you're not sure about; and
Rephrase will try all the alternatives, in all possible combinations, and tell
you which combination (if any) gives you the correct passphrase.
