pgpewrap: Mutt command line munging tool
NAMEpgpewrap - Mutt command line munging tool
pgpewrap [ flags ] -- prefix [ recipients ]
This is a little C program which does some command line munging: The first argument is a command to be executed. When pgpewrap encounters a "--" (dash-dash) argument, it will interpret the next argument as a prefix which is put in front of all following arguments.
This script is needed with PGP 5 and with GPG, since their command line interfaces can't be properly served by mutt's format mechanism.
