| 2 | # |
| 3 | # It describes patterns for python wheel dependencies of the python scripts in |
| 4 | # the chromium repo, particularly for dependencies that have compiled components |
| 5 | # (since pure-python dependencies can be easily vendored into third_party). |
| 6 | # |
| 7 | # When vpython is invoked, it finds this file and builds a python VirtualEnv, |
| 8 | # containing all of the dependencies described in this file, fetching them from |
| 9 | # CIPD (the "Chrome Infrastructure Package Deployer" service). Unlike `pip`, |
| 10 | # this never requires the end-user machine to have a working python extension |
| 11 | # compilation environment. All of these packages are built using: |
| 12 | # https://chromium.googlesource.com/infra/infra/+/master/infra/tools/dockerbuild/ |
| 13 | # |
| 14 | # All python scripts in the repo share this same spec, to avoid dependency |
| 15 | # fragmentation. |
| 16 | # |
| 17 | # If you have depot_tools installed in your $PATH, you can invoke python scripts |
| 18 | # in this repo by running them as you normally would run them, except |
| 19 | # substituting `vpython` instead of `python` on the command line, e.g.: |
| 20 | # vpython path/to/script.py some --arguments |
| 21 | # |
