GnuPG exit codes

[Kurt Fitzner]

I have done some looking at the GnuPG source and it seems to me that
GnuPG only ever exits with a code of 0, 1, or 2.  I just need to confirm
that this is the case and what the exit codes mean.  My interpretation is:

0 = success
1 = processing error - the command line was a correct command, but GnuPG
ran into some sort of problems while trying to complete the task
2 = command error - GnuPG could not start because it could not correctly
interpret the command line

Is this correct?
