Description

In reference to: ​http://docs.djangoproject.com/en/dev/howto/outputting-pdf/

cStringIO is a great way to speed up complex reportlab pdfs. For portability in environments that don't have cStringIO, I would encourage django coders to use this idiom:

try:
    from cStringIO import StringIO
except ImportError:
    from StringIO import StringIO

Added a simple patch that changes the code sample to use the try, except block and a simple explanation of why it's necessary after the code sample.

I'd simplify the explanation to just a parenthetical note that "cStringIO is not avilable in all enviroments, StringIO may be used in it's place in such circumstances".

Updated the patch, now just has a comment above the import with a one line description explaining what's happening.
