This allows you to run:
sh snapaid.sh find amd64 vmdk CURRENT xz 1

and it will automatically d/l the latest vm image that is vmdk, xz
compressed for the amd64 architecture.

Add the script and commands used for this analysis so that I'll remember
it in the future...

full command to import the key to make it easy for people who don't
know gpg well.

Make sure that the necessary keys are present before starting.

Make sure that a failed download will be properly detected and not
leave behind invalid files.

This is a set of scripts to make an index of all the snapshots, and
the message-id of the email that contains the hashes...

There is also the utility itself which uses this index to both find
out what snapshots are available for d/l, and to verify any snapshot
that may have already been d/l'd.
