This one is particularly critical to your intended meaning as I read it: -before a .post345 marker. +before a .post456 marker.

Technical question:

I don't know what notation this versioning schema was trying for, especially in regards to what the +'s mean: N.N[.N]+[abc]N[.N]+[.postN+][.devN+] Am I missing something here? You could maybe explain what the pluses mean in the PEP, and why some are inside the [] and others are outside.

Or a regular expression version like this might be more specific. N.N(.N)?([abc]N(.N)?)?(.postN)?(.devN)?

Or an linux help version like this may be more readible. N.N[.N][{abc}N[.N]][.postN][.devN]
