Thanks.  I was aware of that.  I wanted to know if there were an
easier way. :) I guess this should be a fairly common requirement
anyway so having some boilerplate code would be useful.

It struck me that since Pyste files are pure Python files it would
certainly be useful if a *user* could share common functions that
generate code that is common across Pyste files that they have.  To
this end it would be nice if 'import' could work in the directory
where the .pyste file exists.  So perhaps something like this would be
useful in pyste.py::ParseArguments():

    for file in files:
        d = os.path.dirname(os.path.abspath(file))
        if d not in sys.path:
            sys.path.append(d)


That way any of the .pyste files could import others in their
directory without having to resort to doing it in each of their source
files.

Thanks!
