I'm getting very confused regarding where 'olpc-update' comes from.

The wiki says to get it from http://dev.laptop.org/~cscott/olpc-update/
but here a new version comes with a new build.

[Further, the wiki says to look at --version.  Every time I use 
'olpc-update', it tells me --version is not a valid parameter.]
