+ PEP
+ Python Enhancement Proposal. A PEP is a design document
+ providing information to the Python community, or describing a new
+ feature for Python or its processes or environment. PEPs should
+ provide a concise technical specification and a rationale for proposed
+ features.
+
+ PEPs are intended to be the primary mechanisms for proposing major new
+ features, for collecting community input on an issue, and for documenting
+ the design decisions that have gone into Python. The PEP author is
+ responsible for building consensus within the community and documenting
+ dissenting opinions.
