> On Mac OS X, make sure that your HTML files are terminated by :
>    a line feed (ascii 10) and NOT a carriage return (ascii 13).
> PSP does *not* like lines terminated by only a carriage return.
> The problem was that I was using Adobe GoLive to edit my web pages and to insert the
python code in the page (I am talking about the source view, not the WYSIWYG/Layout view).
 My version of GoLive is a little old and still prefers to write files with carriage return
line endings.  This was the default for the Mac OS before Mac OS X.  Everything *looks* OK
in the GoLive editor and it also looked OK in the other editors I chose to check the code
(other editors would have tipped me off, but I did not use one of those).
> However, it seems that the PSP engine, or whatever you want to call it, does not treat
carriage returns as line endings, and therefore chokes badly when encountering code written
this way.
> GoLive has a menu item where you can select  the desired line terminator.  I selected
"Unix (LF)".  This made no visible change to the document when viewed in GoLive, but then
suddenly the <% ... %> PSP parts of the document worked perfectly. 
> """
> I've confirmed that psp_parser.l expects lines of python code to be terminated with:
"\r\n | \n | %>" so the fix should be a one liner.
