I just tried to write my first recipe on the Cookbook. I ran into the
following problems:
1) I can't attach a .py. I got a message saying I can only attach
text/scripts (when that's what I was attaching).
2) There was no warning that the recipe posted anyway. Afraid that I
lost all that typing, I went back one page and attempted to attach the
script again. I ended up with a duplicate post.
3) My post appears correctly in Edit my recipes, but is corrupted when
actually viewing. Notice that halfway through the jinja_helper.py
section, the body of my recipe is repeated. The offending character
seems to be the < in while len(output) < 6: Replacing the < with <
breaks up the <pre> tag.
