Help! Summarizing the xulrunner situation in OLPC

[Jim Gettys]

Daniel,

It is quiet possible we'll want to pick up gnomevfs2 as a basic library
in a future release (think about the OLPCfs method of accessing the
journal).  We didn't want the old gnomevfs library since that pulled in
the old bonobo horror as a dependency. I'm not familiar with libgnome,
and therefore have no opinion there.
