[lxc-users] clarification

[Worth Spending]

I'm currently reading thru the documentation at: 
https://linuxcontainers.org to learn lxc.

There seems to be multiple ways of running lxc commands.

lxc-start, lxc-stop, lxc-attach, lxc-ls

or lxc with sub commands.

lxc start

lxc stop

lxc list

So, the question is: What is the current preferred usage for lxc 
commands?  hyphenated commands or lxc with sub commands?

Thanks...
