It doesn't say anything about the combination of signing and
encryption, which normally doesn't work correct. Gero's script works
around this problem by first creating a detached signature, then
creating a signed message with this (using some perl tricks and the
--no-literal option of gpg) and after this it encrypts this temporary
message with gpg --no-literal. Don't ask me why this works, but it
works correct for sign+encrypt.
