dim-0.4.8

      - The mount command now adds all files in working dir into the clone index
        tree.
      - Fix a bug in put command, where current item was ignored.
      - Fix a bug in mount due to previous modification.
      Bugfix: the existence of the sum file also required for update_sum().
      - merge dim-0.4.7-mv2-pb1
      - Added the ability to have multiple verbosity levels.
        Use it in add which is non verbose by default when called
        by mount, unless explicit -v.
      - Fix multiple argument processing in add/del.
      - After any deletion in index, force full update_sum.
      - "dim anc -M" returns the main branch ancestor.
      - "dim dag -M" diplays a graph rooted as the main branch anc.
      - 'dim version -a' dies as it should when outside of a job.
      - 'dim mkitem Item' dies as it should when Item already exists.
      - 'dim merged Vers' was broken and has been fixed.
      - Fixed a bug in plog(), that caused log files to grow out of control.
      - plog() is still broken, but does not cause export to run out of memory.
      - Merge dim-0.4.7-mv4-pb3
      - New -o auto|noauto option for (re)mount
      - update_sum scan for add/del files in auto mode (not perfect).
      - 'dim mkitem Item' dies as it should when Item already exists.
      - 'dim merged Vers' was broken and has been fixed.
      - Performances in "auto" mode are improved.
      - Handling of removed files is fixed.
      - Fix 'dim export [-n] -B xxx' which was generating a wrong name
      - 'dim mount' reports auto or noauto.
      - 'dim remount' removes the scan file.
      - Handling of -o option has been cleaned up.
      - 'dim export' do not change modify the extern ancestor. One has to
      - run 'dim remount' prior exporting to adopt a different ancestor (for
        example on the main branch).
      - 'dim add' uses the scan file only when it exists.
