- Major rewrite of this tool:
  
  Uses the officially support version P4Perl 2008.2
  mkdepot.pl now only uses one connection to the Perforce server in tagged mode.
  Branching enabled. This was never properly implemented and partly disabled. 
  Branching should work now as expected.

1999/12/15

- fix to handle setting client root when it contains spaces

- fix verification script to use p4 fstat rather than p4 where, and to
  do the appropriate song and dance to verify keyword expanded files

1998/8/14

- fixed date format problem with 98.2 (p4 change -f would fail on dates of
  the form yyyy/mm/dd  h:mm:ss - i.e. times before 10am)
- other small updates

1998/6/5

- added support for ignoring branches (useful if PVCS branches aren't labelled
  and aren't terribly meaningful anyway)
- added support for not including a branch name in depot filenames
  (not recommended but it might be useful for some)

1998/3/24

- added support for lowercasing user names
- added ability to specify file type by "filename extension"

1998/3/19

- added ability to log complete output of all commands run by the converter

  warning message

1998/3/11

- added support for "level 2" branching, removed code to run "p4 branches"

  if they are set

1998/3/5

- fixed convert.pl to recognize files ending in V as well as v  (Doh!)
- added support for lowercasing filenames and paths
- improved error logging and error checking
- added a verification script (verify.pl)
- removed support for servers prior to 97.3 in order to
  - eliminate the p4 get in mkdepot.pl (this speeds things up and avoids a
    possible future incompatibility)
  - remove code to support not using p4 change -f

1998/1/21

- fixed mkdepot.pl to handle multiple labels on same revision
