Note documentation at: https://www.chromium.org/developers/testing/gpu-testing. 

The problem is two fold. 

1. I'm guessing that some underlying infrastructure has changed with regards to finding modules/whatever and the public documentation was never updated.
2. help appears broken, and I keep pylint output?

If help worked and I could figure out how to run some gpu tests locally, I could update the public documentation. But I'd rather not dig through lots of telemetry code right now.

  Master:
    --rcfile=<file>     Specify a configuration file.
    -E, --errors-only   In error mode, checkers without error messages are
                        disabled and for others, only the ERROR messages are
                        displayed, and no reports are done by default
    --py3k              In Python 3 porting mode, all checkers will be
                        disabled and only messages emitted by the porting
                        checker will be displayed
    --ignore=<file>[,<file>...]
                        Add files or directories to the blacklist. They should
                        be base names, not paths. [current: CVS]
    -j <n-processes>, --jobs=<n-processes>
                        Use multiple processes to speed up Pylint. [current:
                        1]
    --extension-pkg-whitelist=<pkg[,pkg]>
                        A comma-separated list of package or module names from
                        where C extensions may be loaded. Extensions are
                        loading into the active Python interpreter and may run
                        arbitrary code [current: none]

  Commands:
    --help-msg=<msg-id>
                        Display a help message for the given message id and
                        exit. The value may be a comma separated list of
                        message ids.
    --generate-rcfile   Generate a sample configuration file according to the
                        current configuration. You can put other options
                        before this one to get them in the generated
                        configuration.

  Messages control:
    --confidence=<levels>
                        Only show warnings with the listed confidence levels.
                        Leave empty to show all. Valid levels: HIGH,
                        INFERENCE, INFERENCE_FAILURE, UNDEFINED [current:
                        none]
    -e <msg ids>, --enable=<msg ids>
                        Enable the message, report, category or checker with
                        the given id(s). You can either give multiple
                        identifier separated by comma (,) or put this option
                        multiple time. See also the "--disable" option for
                        examples.
    -d <msg ids>, --disable=<msg ids>
                        Disable the message, report, category or checker with
                        the given id(s). You can either give multiple
                        identifiers separated by comma (,) or put this option
                        multiple times (only on the command line, not in the
                        configuration file where it should appear only
                        once).You can also use "--disable=all" to disable
                        everything first and then reenable specific checks.
                        For example, if you want to run only the similarities
                        checker, you can use "--disable=all
                        --enable=similarities". If you want to run only the
                        classes checker, but have no Warning level messages
                        displayed, use"--disable=all --enable=classes
                        --disable=W"

  Reports:
    -f <format>, --output-format=<format>
                        Set the output format. Available formats are text,
                        parseable, colorized, msvs (visual studio) and html.
                        You can also give a reporter class, eg
                        mypackage.mymodule.MyReporterClass. [current: text]
    -r <y_or_n>, --reports=<y_or_n>
                        Tells whether to display a full report or only the
                        messages [current: no]
    --msg-template=<template>
                        Template used to display messages. This is a python
                        new-style format string used to format the message
                        information. See doc for all details
