Snap vs Snappy

[Jacob Humphrey]

Hello,

     I'm sorry if this has already been covered, but I couldn't find 
anything in the archives. Currently the snapd package for xenial 
contains the command "snap", which is used to manage snaps; however all 
of the documentation on the Ubuntu site refer to the command "snappy", 
which has the same purpose, but slightly different syntax.

     Is there a reason we have these two commands for the same purpose? 
Also, if "snap" is the command that is used in xenial, why do we not 
have documentation for it? I'd appreciate any clarification on this matter.

Thank you,
Jacob Humphrey
