Note that, as part of adding this packages to the automated vendoring system, some dependencies were automatically added - most notably, dependencies of `taskcluster` that become visible with Python 3.6+. Also, adds `**/.git` to the exclusions because: * `.git` is part of our `.hgignore`, but * `.git` is part of the `aiohttp` `tar.gz` file. Since the file isn't needed for `pip install`-ing `aiohttp`, and since we want `./mach vendor python` to be a no-op when there's no requirement changes, we exclude it.

Example of serving an Application using the `aiohttp.web` CLI.
|
|
|
|
Serve this app using::
|
|
|
|
$ python -m aiohttp.web -H localhost -P 8080 --repeat 10 cli_app:init \
|
|
> "Hello World"
|
|
|
|
Here ``--repeat`` & ``"Hello World"`` are application specific command-line
|
|
arguments. `aiohttp.web` only parses & consumes the command-line arguments it
|
|
needs (i.e. ``-H``, ``-P`` & ``entry-func``) and passes on any additional
|
|
arguments to the `cli_app:init` function for processing.
