A quick grep reveals some test examples in test_platypus_pto.py which 
generate three files "test_platypus_KeepInFrame*.pdf".

However there's a much better explained RML test case which should show 
the intended use:

http://developer.reportlab.com/rsrc/rml_examples/test_029_keepinframe.pdf

It's most useful in fact sheet layouts where you might have, say, five 
locations ona page for specific chunks of content, and be want to sure 
that the stuff destined for "leftColumn" really goes there.  When the 
story encounters one of these, it skips to the named frame if not 
already there, and ensures all content fits.    If there is too much 
content it will overflow, shrink, truncate or raise an error.

Hope this helps,
