The PEPs in this repo are published automatically on the web at
http://www.python.org/dev/peps/. To learn more about the purpose of
PEPs and how to go about writing a PEP, please start reading at PEP 1
(pep-0001.txt in this repo). Note that PEP 0, the index PEP, is
now automatically generated, and not committed to the repo.
See the Contributing Guidelines.
Original PEP source should be written in reStructuredText format,
which is a constrained version of plaintext, and is described in
PEP 12. Older PEPs were often written in a more mildly restricted
plaintext format, as described in PEP 9. The pep2html.py
processing and installation script knows how to produce the HTML
for either PEP format.
For processing reStructuredText format PEPs, you need the docutils
package, which is available from PyPI.
If you have pip, pip install docutils should install it.
PEP 0 is automatically generated based on the metadata headers in other
PEPs. The script handling this is genpepindex.py, with supporting
libraries in the pep0 directory.
Do not commit changes with bad formatting. To check the formatting of
a PEP, use the Makefile. In particular, to generate HTML for PEP 999,
your source code should be in pep-0999.rst and the HTML will be
generated to pep-0999.html by the command make pep-0999.html.
The default Make target generates HTML for all PEPs.
If you don't have Make, use the pep2html.py script directly.
python.org includes its own helper modules to render PEPs as HTML, with suitable links back to the source pages in the version control repository.

When making changes to the PEP management process that may impact python.org's rendering pipeline:
- Clone the python.org repository from https://github.com/python/pythondotorg/
- Get set up for local python.org development as per https://pythondotorg.readthedocs.io/install.html#manual-setup
- Adjust
