Why are PEPs converted to HTML at all then? (Semi-seriously :-)
RFCs pre-date the Web, HTML, GUIs, and PCs. There is a great advantage in
sticking to a text-based format, but the existing structure is very limited.
RFCs are so 20th century; don't you think it's time to move on? ;-)
Dinosaurs have a tendency to become extinct you know.
Given a small amount of use, I think you'll find the rules easy to remember.
There should be little effect on editing. At most, Emacs may need to be
taught to recognize a bit more punctuation.

It's a trade-off: functionality for markup intrusion. It's the
functionality of the processed form that's important: inline live links;
live links to & from footnotes; automatic tables of contents (with live
links!); images (don't you just *cringe* when you see ASCII graphics?);
pleasant, readable text. The markup is minimal, quickly and easily ignored.

Sure. I thought I'd emphasized that in my original post: it'd be an
alternative, the two styles can coexist. If you want to keep PEP 0 as it
is, that's fine. I converted it to show that its special processing was

I'm not keen on a new file extension (this issue has come up before).
There's so much in place on many platforms that says .txt means text files,
and reStructuredText files *are* text files, with just a bit of formal
structure sprinkled over. Browsers know what to do with .txt files; they
wouldn't know what to do with .rest or .rtxt files. Near-universal file
naming conventions are not the place to innovate IMHO.

See http://docutils.sf.net/tools/pep2html.py (based on revision 1.37 of
Python's nondist/peps/pep2html.py). Other than abstracting the file I/O and
some minor changes for consistency & legibility, the
reStructuredText-specific part is just two functions. One checks for the
format of the PEP, and the other calls Docutils to do the work. Even
without a new file extension, there's no need for a separate tool.

Do we need a slightly less-structured text output? I don't think so, but I
offered two alternative strategies in PEP 287:
a) Keep the existing PEP section structure constructs (one-line
section headers, indented body text). Subsections can either
be forbidden, or supported with reStructuredText-style
underlined headers in the indented body text.
b) Replace the PEP section structure constructs with the
reStructuredText syntax. Section headers will require
underlines, subsections will be supported out of the box, and
body text need not be indented (except for block quotes).
Strategy (b) has been implemented; that's what the edited PEP 287 uses. I'd
recommend against it, but if you insist on existing PEP structure, strategy
(a) fits better although inconsistently (depending on the decision on

Sure. Once authors see what the new markup gives them, I'm sure there will
be some converts.
