Lib/argparse.py [1] doesn't mention a license in it. Could you please add a license to it?

According to the argparse project [2], argparse is licensed under the Python license. Chromium OS uses argparse. If you would add information about the license to argparse, we'd appreciate it.

Here's an example license string that passes the Debian licensecheck [3] script:

# Licensed under the Python Software Foundation License version 2.7


In case you don't understand why Chromium wants include a license in argparse.py, rather than just consulting the global LICENSE file, here's a bit more detail: Chromium includes many files from different authors in its distribution. Many projects contain LICENSE files, but this doesn't mean that every file under the project is licensed under that license. So it's helpful if each file has a quick note that mentions what license it uses. This helps us ensure that we understand the license of all files we include. We automate this check using  Debian's licensecheck.pl script.
