When you move or rename the directory, its .arch-ids subdirectory moves
with it.  The ids contained within will still match their files and so tla
is able to detect that the directory was renamed and the files within were
moved. 

You don't need a "tla move" to handle directory renames.

By "transparent", Robert meant that none of your tools moving and renaming
files need to understand that the file is version controlled.  It also
means that you won't need to care either.  (A copy will act strange, but
the tree-lint run by commit will whine at you.)

With taglines, you don't need to "tla move" anything.  "mv" or whatever
your GUI file manager does will do the right thing.
