    Translate a cURL command created by Chrome's developer tools into a

    Parameters
    ----------
    curl_cmd
        The string given to you by the "Copy to cURL" context action in
        Chrome's developer tools.

        The number of concurrent requests ApacheBench should make

    ----
    Not all headers play nice with ApacheBench, so ``headers_to_copy`` has
    been set to a reasonable default. Tweak this if you need something

Thank you! Consider changing line 1 to

#!/usr/bin/env python2

as tf.write(curl_cmd[i+1]) fails under Python 3.

Thank you! Consider changing line 1 to

Thanks, I've updated that line to work in both Python2 and Python3, I tend to avoid breaking compatibility when I don't really need to :-)
