Well, tla get works, which is very reassuring.

Is there a problem with editing history if there is a subsequent
changeset in my archive?

Firstly, from within .../patch-43/ I edited log and checksum.

Firstly log, to make the summary reasonable, then ran md5sum
against log, and inserted its output into checksum (replacing
the old checksum).

Then I blew away my current two working trees and ran
"tla get $zenat tla", "cd tla" and ran "tla logs -scD".
The output includes the following:

    2004-09-22 05:48:23 GMT      Zenaan Harkness <address@hidden>
    arch patch-3 + misc
    2004-09-23 02:02:50 GMT      Zenaan Harkness <address@hidden>
    2004-09-23 03:33:38 GMT      Zenaan Harkness <address@hidden>
    new: conf/alii for archives aliases; fix: bad usrname propagation; DEBUG2 = 

So it appears that after all that, the log still hasn't
changed somewhere. Any idea what is getting away from me?
