Tile 0.8.0 will have a transition strategy for all the
public routines that got renamed; and will still include
the treeview widget.

I'd recommend including both in the Tk 8.5 beta, but that's
up to Jeff.

OK, here's what's happening:

Tk 8.5a6 does not provide (in the sense of [package provide])
"tile" or "Ttk" packages, so [package require tile] ends up
loading tile.so and calling Tile_Init().

Tile_Init() in turn calls Ttk_StylePkgInit(); however, on
ELF-based systems, this gets resolved to the version of the
routine in the core, not the version in tile.so.  Since the
core provides an API that's incompatible with Tile 0.7.X,
the scripts in $::tile::library raise an error.  (This might
cause other problems as well, but that's the main one).

Consequently: any existing programs that call [package require tile]
will fail when run with Tk CVS HEAD on ELF-based systems.

Windows (and, I believe, OSX) aren't affected, since shared
libraries work differently there.
