The problem

Current ("old-style") configuration files use a custom syntax, of the form

..code::conf

Current ("old-style") configuration files use a custom syntax, of the form ::

Maintain a matplotlibrc-like syntax

The config files would maintain the format

..code::conf

The config files would maintain the format ::

discussion that took place overPEP518_ (not that I particularly like the

final choice of yet another obscure configuration language by that PEP).
