Furthermore, applications are well advised to use libext2fs instead of
trying to roll their own access routines.  Libext2fs has been in
development for over ten years, and as such as all sorts of nice
features, including regression test suites, byte swapping so the code
will work on big-endian systems, portability to non-Linux systems, etc.

Using libext2fs also means that it's much more likely the application
will require less work to support ext4 in the future.  If there's
something that ext3grep needs where some existing libext2fs function
provides almost, but not quite, the needed functionality, talk to me;
right now there's quite a bit of development going on with e2fsprogs,
and it's likely I can add the needed support in the next version of
the library.
