-----BEGIN PGP SIGNED MESSAGE-----
The gnu tar archiver allows to use an arbitrary
compression program (option --use-compress-program=PROG).
This works well with pgp if a small wrapper is used:
#!/bin/csh -fb
if ("$1" == "-d") then
exec pgp -d -f
else
exec pgp -e -f
endif
The only problem is that this doesn't work well for
larger amounts of data, because pgp reads in all
data before starting with its work.
Perhaps a future release of pgp will have a real filter
mode.

BTW: Does this "crypto-hook" cause export restrictions to
apply on gtar ?
