   # These revisions are slices of the chromium repository.
   # Because they come from separate sub-slices, their hashes do not match at
   # equivalent revisions. When updating them, use the roll-dep script
   # to move them to equivalent revisions. Additionally, because not all
   # directories contain commits at each revision, you will need to select
   # revisions at latest revision up to a high watermark from each slice.
   # Document the high watermark here:
   # chrome_rev: 275800

   # NOTE!  These five should be kept up to date with their counterparts in
   # chromium/src/DEPS.
   # Be sure to update them when updating the chromium slice revisions above.
   # (This is not essential for Breakpad, because we do not use its code
   # in the build that goes into Chromium.  But we might as well update it too.)
   # You should now use the roll-dep script in depot_tools to do this update.
