MD5 (gen-key-batch.gz) = 4409429759af233af7b27fb94b1e1c1e

the script is *crude* and lacking comments, but attached. it writes each 
key-pair to it's own public/private files, using the current date/time as 
a prefix: if it generates keys faster than 1/second, files will get 
clobbered, using the current naming convention.

as is, it generates a sign+encrypt RSA primary key with NO subkeys, and a 
finite life. read the docs and you'll see how to generate a more common 
DSA/ElGamal key.

if you want to generate 20 keys (all with the same UID) just run:
 	$ ./gen-key-batch 20

there a section (Unattended key generation) in doc/gnupg/DETAILS that goes 
into the the options and how to set them.
