| # This is a vpython "spec" file. | 
 | # | 
 | # It describes patterns for python wheel dependencies of the python scripts in | 
 | # the chromium repo, particularly for dependencies that have compiled components | 
 | # (since pure-python dependencies can be easily vendored into third_party). | 
 | # | 
 | # When vpython is invoked, it finds this file and builds a python VirtualEnv, | 
 | # containing all of the dependencies described in this file, fetching them from | 
 | # CIPD (the "Chrome Infrastructure Package Deployer" service). Unlike `pip`, | 
 | # this never requires the end-user machine to have a working python extension | 
 | # compilation environment. All of these packages are built using: | 
 | #   https://chromium.googlesource.com/infra/infra/+/master/infra/tools/dockerbuild/ | 
 | # | 
 | # All python scripts in the repo share this same spec, to avoid dependency | 
 | # fragmentation. | 
 | # | 
 | # If you have depot_tools installed in your $PATH, you can invoke python scripts | 
 | # in this repo by running them as you normally would run them, except | 
 | # substituting `vpython` instead of `python` on the command line, e.g.: | 
 | #   vpython path/to/script.py some --arguments | 
 | # | 
 | # Read more about `vpython` and how to modify this file here: | 
 | #   https://chromium.googlesource.com/infra/infra/+/master/doc/users/vpython.md |
