    Hello,

    For my application (http://onefinger.sf.net), which is a wrapper over bash,
    I have to be able to parse a command line typed by the user.

    I.e., I need a function that, when given a typical bash command string like

    mplayer -sub /usr/a\ good\ movie.srt "/home/a good movie.avi"

    , outputs a list of python strings (tokens):

    [ "mplayer", "-sub", "a good movie.srt", "/home/a good movie.avi"]

    Writing this function doesn't seem easy to me: it seems I must split the
    string when I encounter a space/tab, but not if the space/tab is enclosed
    into quotes... furthermore, I have to remove the quotes (notice the last
    token in the string has the quotes removed).

    Do you know some python library I can use? Or is there an easier way?

    PS: The current implementation is broken when the user writes quotes.

    Thanks for any help,
