0. Requirements

    tch.py requires python version 2.5 or newer to run
    (although perhaps it can be fixed to run with older
    versions by adding "from future" statements).
    Versions for many different platforms can be
    downloaded from http://python.org/download/ or
    installed via the preferred package manager
    for your OS.

1. Installing

1.1 Unix/Linux

    Unzip tch.py, make sure it is executable, copy it
    to the directory where you want it to run from,
    e.g. (if you have root access and want other users
    to run it):

    $ unzip tch-0.1.0.zip && cd tch-0.1.0 && chmod a+x tch.py && sudo cp tch.py /usr/local/bin/

    If you have multiple versions of python installed
    and `python` command on your system runs an older
    version of python (try `python --version`) you'll
    need to change the first line of the tch.py, e.g:

    #!/usr/bin/env python2.5

1.2 Microsoft Windows

    Unzip the tch.py file somewhere.

2. Running

2.1 Unix/Linux

    $ /path/to/tch.py

    or if you copied tch.py under your $PATH simply:

    $ tch.py

2.2 Microsoft Windows

    Start -> Run -> cmd [Enter]
    X:\Path\To\python.exe Y:\Path\To\tch.py

    NOTE: Associating .py files with python.exe seems
    not to work with piping, not sure.
