which software can able to cut or split mkv video files?

which software can edit mkv format video files without re-encode?
for example:for avi videos, there is avidemux tool:crybaby:

I think there is a software called VideoCharge Studio that can convert mkv files to flv files without re-encoding the video files. Also you can recode only a sound or a video stream or both of them. These are similar kind of basic functions that you will get, but it also lets you add watermarks to your videos, make edits, create thumbnails of each of your videos, improve the quality of your movies, create sites for online publish of your collection of video, add effects, etc.
