I just did too. I've been working with liblvm2cmd for a day and a half
and began working backwards through tools/ to see how things worked.

Thanks to all who made liblvm2cmd which makes things much simpler for
those who are just getting their first glimpse of things. It is going to
take some time to digest the rest.
I found liblvm2cmd by accident, really. I grabbed the source to LVM2
while in search of a more elegant way to use LVM in other programs
without resorting to system() or exec*() calls.
