Based on Python docs:

"""
argv

    The list of command line arguments passed to a Python script.
    argv[0] is the script name (it is operating system dependent whether
    this is a full pathname or not). If the command was executed using
    the -c command line option to the interpreter, argv[0] is set to the
    string '-c'. If no script name was passed to the Python interpreter,
    argv has zero length.
"""

http://docs.python.org/lib/module-sys.html

In my opinion, this would be enough to get full path of currently
running program, if run from script. Are there any caveats (except this
"-c" option, which I don't count, as is not relevant in most cases)?
