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...

revisions...

This likely messes up formatting, and those fixes will be next...

This should make it much easier for people to run their own version
if they'd like to..

for RELEASEs...

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

include vm type for RC/BETA

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.

Add the complete option to complete and finalize the indexes after
a larger -m run...  I've been rebuilding the indexes a lot as I

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.
