Bah, that was *supposed* to be a test of the different flavors of
metadump (copy entire blocks or not; obfuscate names or not) but clearly
I thinko'd the metadump commands. :(
Where is this AI programming future where I can simply express a desire
to test all the major format-altering metadump variants and the computer
will figure out what needs to be done, rather than me having to write
that idea in triplicate in the form of a log message, a file name, and a
command line switch?
It's times like these I really hate programming. <grumble>
