OK.  I'll change it to update the mtime after extraction, and create the 
canary file at extraction time (which is simpler in any case).

I'll also separate out the other components of the patch as separate 
issues (the meta.yml quoting and verbosity levels needed for -add-files).

Is there an alternate repo?  svn.openfoundry.org has not been responding 
for the last 24 hours, perhaps more.  Otherwise I'll wait for it to come 
back online to update my repo to the latest par sources before starting.

Shawn.
