CheckDirMetadataFormat executes dirmd on all applicable files. When running "git cl presubmit --all" that ends up being ~7,500 files and the command line that is generated is ~500,000 characters. Windows does not like that. This change breaks up the check into multiple invocations of dirmd in order to avoid these limits. This is important because running all presubmits is the only way to systematically find bugs, and avoid being surprised by them when submitting a change.

Usegclient helpfor more details and README.gclient.md.git cl: A code review tool to interact with Rietveld or Gerrit. Usegit cl helpfor more details and README.git-cl.md.roll-dep: A gclient dependency management tool to submit a dep roll, updating a dependency to a newer revision.
There are a lot of git utilities included.
Updating
depot_tools updates itself automatically when running gclient tool. To

cpplint.py
Until 2018, our cpplint.py was a copy of the upstream version at
https://github.com/google/styleguide/tree/gh-pages/cpplint. Unfortunately, that
repository is not maintained any more.
If you want to update cpplint.py in depot_tools, just upload a patch to do
so. We will figure out a long-term strategy via issue https://crbug.com/916550.
Note that the cpplint.py here is also used by the Tricium
analyzer,
so if the cpplint.py here changes, we should also update the copy used there.
