Possible to recover data in .gdbm files?

["Dana R. Canfield" <canfield@uindy.edu>]

I made a typo and managed to blow away my index2entry file.  I have a
backup, so it's not the end of the world, but this backup is old enough
that there is were probably a significant number of changes.  All of the
other .gdbm files are still intact.  Is there any way to either rebuild
the index2entry file based on these other files, or to at least get the
info in the other files into some format so that I can somehow manually
replace some of the data?

Any other suggestions would also be greatly appreciated.
