Python course redistribution licence

The licences under which we've released both the worksheets and the LiveWires Python package are intended to allow other people to copy and modify our work. Unlike commercial software licences, they're not intended to restrict your freedom to copy the sheets and software, rather, they're intended to encourage copying.

The restrictions that do appear in the licence are intended to ensure that we retain copyright on our work, get credit for it and do not get sued for it.

The licences for both the sheets and the LiveWires package are quite similar. They both allow free distribution of unmodified copies of the package and sheets (as long as the text of the licence is also distributed with them somehow).

If you're distributing printed bundles of worksheets, we suggest providing a cover sheet with the licence on it. If you're distributing only binary files (for example, opaque documents, .pyc files or frozen binaries), you must include the relevant copyright notices and licences with the binaries (this is usually done by putting a text file containing the necessary information in the archive). If you're distributing source, it's usually easiest just to embed the licence in the source files.

If you modify the package or sheets and want to redistribute your modifications under the same licence as we've used here, the best way is to add your name to the relevant copyright notices. Note that the documentation licence requires that you maintain the existing copyright notices in both the opaque and transparent forms of the document.

We don't force you to distribute any additions you make to the course under the same licences as we've used. As long as you comply with our licences, you can distribute binary only versions of the work, say. We'd like it if you did use a free licence to contribute your changes back into the community, though.

Note: The licences do require permission before you use the LiveWires name in advertising a modified work derived from the work we've released here. Ask us, though, as we're likely to say yes.

We welcome corrects, enhancements and helpful comments. See the credits page for how to get in touch with us.

THE LIVEWIRES DOCUMENTATION LICENCE

COPYRIGHT NOTICE:

[The document copyright notice goes here.]

CONDITIONS:

A "Transparent" form of a document means a machine-readable form, represented in a format whose specification is available to the general public, whose contents can be viewed and edited directly and straightforwardly with generic text editors or (for images composed of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a variety of formats suitable for input to text formatters. A copy made in an otherwise Transparent file format whose markup has been designed to thwart or discourage subsequent modification by readers is not Transparent. A form that is not Transparent is called "Opaque".

Examples of Transparent formats include LaTeX source and plain text. Examples of Opaque formats include PDF and Postscript. Paper copies of a document are considered to be Opaque.
