Dinu -

Thank you for a very useful and useable tool.  I use pypdf.py
frequently to produce displayable sample code for students to whom
I'm teaching Python.  I hope you will continue to support it.

I've made a couple of changes to my copy of py2pdf.py.  I'd like to
suggest that you consider including these changes.  The changes
are:

1. I'd like to be able to add the ".pdf" extension to file names
   rather than replace the ".py" with ".pdf".  So I added command
   line flags to control that.

2. I'd like line numbering to start with 1 rather than 0.  I
   hard-wired that into py2pdf.py.  Maybe, if you choose to support
   this, you would want to add a command line flag, for example,
   something like --initial-line-number, along with a default of
   0 or 1, whichever.

I've attached a patch file and the original to which I made my
changes.  Needless to say, you know py2pdf.py better than I and are
likely to know better ways to make these changes.  Still, I'm
hoping that a patch file will save you some work.

Thanks again for a really good tool.

- Dave
