The code and comments should be self-explanatory, but a few things deserve a
mention:
* The response gets a special MIME type, :mimetype:`application/pdf`. This
tells browsers that the document is a PDF file, rather than an HTML file.
If you leave this off, browsers will probably interpret the output as
HTML, which would result in ugly, scary gobbledygook in the browser
window.

* The response gets an additional ``Content-Disposition`` header, which
contains the name of the PDF file. This filename is arbitrary: Call it
whatever you want. It'll be used by browsers in the "Save as..."
dialogue, etc.

* The ``Content-Disposition`` header starts with ``'attachment; '`` in this
example. This forces Web browsers to pop-up a dialog box
prompting/confirming how to handle the document even if a default is set
on the machine. If you leave off ``'attachment;'``, browsers will handle
the PDF using whatever program/plugin they've been configured to use for
PDFs. Here's what that code would look like::

* Hooking into the ReportLab API is easy: Just pass ``response`` as the
first argument to ``canvas.Canvas``. The ``Canvas`` class expects a
file-like object, and :class:`~django.http.HttpResponse` objects fit the
bill.
