pycurl is a python binding for liburl. For most of the options in libcurl there is a corresponding on in pycurl. But I can not find the ones for CURLOPT_ACCEPT_ENCODING and CURLOPT_TRANSFER_ENCODING.
By the way, I am using ubuntu 13.04, and pycurl version is 'libcurl/7.29.0 GnuTLS/2.12.23 zlib/1.2.7 libidn/1.25 librtmp/2.3'
