Generating sha1 and md5 files

[Marilyn Sander -X \(marilysa - Digital-X, Inc. at Cisco\)]

In the "Guide to Relocation" file, one step in relocation is
 
"5.  If your project uses MD5 or SHA1 checksums you must now create new
checksums for the pom files in /bar/foo in your Maven 2 repository.  If the
pom file needs to be signed, do that as well."
 
I've been searching all over the documentation, also in the BBwM, and cannot
find how to generate those files.  Can someone please tell me where to look?
Is there any way to do it directly, without by running mvn deploy?
 
thanks,
