I don't understand why you need this tool. Debugfs is a more general
tool that will do pretty much everything your proposed e2wreck tool
will do.
The one exception to this is low-level extent tree modifications ---
that functionality is there in the tst_extent program, which is a
debugging program I used when developing the extent support for
e2fsck. Go to the lib/ext2fs directory, and run "make tst_extents".
It's been on my todo list to get a more cleaner support for low-level
extent manipulation to debugfs, but I haven't gotten around to it,
since tst_extents is a serviceable enough, if hacky, substitute.
