gnupg and multiple keyrings

[Tom Parquette]

Hi.
I've been playing with gnupg trying to get comfortable with it.
I've looked at the man pages and I have also read the O'Reilly PGP book.
I searched the FreeBSD mailing lists and I didn't find anything.

I'm trying to create multiple public key rings because of statements in 
the PGP book about performance problems with single, large, public key 
rings.

To test, I created a normal public key ring then I tried to create a 
FreeBSD public key ring using the --keyring FreeBSD option to GPG.

No matter what I do, everything seems to end up in the single public key 
ring.

Can someone help me understand this behaviour?
TIA...
