Bummer. So it seems that even on cygwin open files cannot be
overwritten. This is a problem on W32 (Karl, look! ;-), and I thought
that this might not be a problem on cygwin, but it is.

The problem is that tlmgr is currently running and you try to replace
itself. That works on unix where opened files can be replaced/changed,
but W32 is just to incapable to allow that.

No, see above.

Not easy, because you have to:
- make a full svn checkout
- add your binaries to Master/bin/i386-cygwin/
- call 
	Master/tlpkg/bin/tlpsrc2tlpdb -all
- then call
	Master/tlpkg/bin/tl-update-containers ...with...some..args...

Some details are explained in tlpkg/doc/repository-setup.txt

Best wishes
