Python tomography tool
Pytomo is a YouTube crawler designed to figure out network information out of YouTube video download.

In order to provide installation-free package, we provide binary executables for Linux (32 and 64bits), Windows, and Mac OS X. The binaries files were generated with Pyinstaller (version 1.5RC1).
If you have Python installed, you can directly run the start_crawl.py script at root or the pytomo script in bin directory.
We based the lib_youtube_download on YouTube Download script: we simplified it at most and include only the classes we needed (and only YouTube video retrieval).
The extraction of metadata out of video files is an adaptation of Kaa Metadata Python Package: it has been modified in order to be independent of Kaa-base (thus pure Python and portable).
