Make two (or more) page templates: one for the first page (call it "first")
and and one for the subsequent pages (call it "rest").  Early in the
story, somewhere that would definitely occur one page one,
put in this:


The next new page that begins will use the name 'rest'.

reportlab/test/test_platypus_indents.py and
reportlab/test/test_platypus_leftright.py contain examples of
template changes.  The output PDFs will go in your temp directory.

You can also (since a few months back) add a LIST of templates
so it can do alternating left and right pages for you.  e.g.

If you need dynamically adjusted margins for some reason,
hacking margins on SimpleDocTemplate is highly unlikely to work
as it's a wrapper which constructs a single 'real' page template object
with one frame.  If you use BaseDocTemplate, and hack the frame list,
it might work; but the PageTemplate is reused and not rebuilt each time
so care is needed.

Hope this helps,
