svn for version control on Mac LyX 1.6.1

[John T. Hale]

Hi, I have been using subversion for collaborative authoring with  
LaTeX, issuing lots of evil red text into Emacs and repeatedly typing  
"pdflatex" at the unix prompt. I'd like to trade up to LyX. I see in  
section 7.4 of the HOWTO that Mac-LyX supports RCS. But there was also  
a mention (point 29) in the LyX 1.6 release notes of support for svn,  
as well. I'm not sure how to unleash Pavel's functionality, though.  
Presumably some option needs to be altered to issue commands like "svn  
checkout" rather than "co".

Is there a way to use Subversion on Mac LyX 1.6.1? I have Mac OS X  
10.5.5.

best,
