Ttk is the Tile extension integrated into Tk as approved in TIP #248 [L1 ].
This page details the transition from the existing Tile extension to Ttk package inside the Tk source base.
The Ttk package will be a static package inside Tk. It will not be made a separate binary library. It will use the ttk:: namespace for the most part, sharing the tk:: namespace where appropriate. The classic Tk widgets will all be referenceable from the tk:: namespace, in addition to remaining as toplevel commands (for 8.x at least).

JE What mechanisms (if any) do you intend to use to keep the two codebases in sync after the merge? Parallel DARCS repositories on top of the Tile and Tk CVS repositories might be one solution.
JE Also: it's worth considering removing some or all of tk/generic/tkStyle.c (TIP#48 support)

JE The *.tcl files in tile/tests (except for all.tcl) are mostly small interactive tests that I used during development. There's no real need to import them into the Tk CVS repository.
