Actually, that's one of the context menu options winrar suggests -
the name of the zip file.

Sorry, should have been "." IOW I unzipped it into the dir it was
saved in and let winrar create a dir named after the zip archive.

As it says at your site, Python folks are nice - liked the success
matrix bit, too :) i.e., the "...two ways into..." article linked
from the home page.

Done. Even tried D:\reportlab-1_19\reportlab after the above line
failed - just in case. Erm... I just shut down and started python
again and it reread the path file and works. Screw myself :( Recall
I mentioned shutting it down once before? Maybe I didn't do that
often enough. Wish I knew, cause this has been what I'd call a PITA
compared to the last time I installed this package.

Mekes sense. Python finds what is now paths.pth in the same dir as
its executable, etc.

Maybe not, but it'll save a post later.

Agreed and duly noted. How can I forget after this? ;)

But the userguide.pdf has bullets and paragraphs in that section and
I'm sure you're not talking about graphics_reference.pdf. THe report
lab site I downloaded from... sparse. I didn't see add'l docs there.

If you don't see the pdf manual you expected or you wich to
ensure an up to date copy run the script tools/genAll.py!
"
genALL.py is not in tools\, it's in docs\ - where the readme resides
:) heh, heh... documentation's a bitch.

test_pdfgen_general.py seems to work nicely. runAll.py throws no
errors and compiles __init__.py, unittest.py, and utils.py.

genAll.py threw a flurry of messages some WARNs some Errors. I tried
to redirect win console errors to a file, but all those python
errors don't make it there. The first wrning was that the Imaging
Library was not available. Unable to import bitmaps.

Maybe that means PIL? I dunno.

I got graphics_reference.pdf out of the deal. Not sure if there
should be more, but the 00readme says

"
Thid directory holds documentation.  For end users,
it should contain a number of PDF manuals.  For
people working with the source, this directory will
be the destination for any manuals built.

Is that part of reportlab or what? FYI, reportlab is used by a
program called gerber2pdf by Joseph C Chavez. It converts the
industry standard Gerber files from an electronic circuitboard
layout package to pdfs. Kinda handy when you don't have a high $
photoplotter.
