[tex-live] "TeXLive" or "TeX Live" in documentation?

[Br. Samuel Springuel]

In working with some documentation updates for a package I help maintain 
(Gregorio), I noticed that we fairly inconsistently switch back and 
forth between "TeXLive" and "TeX Live".  Is there a preferred format for 
the name of the distribution that we should be using?
