[Matplotlib-users] Capitalization of Matplotlib

[Benjamin R. <ben...@ou...>]

I am in the final rounds of edits for my book and a question has come up
between me and the editors. When should the matplotlib be capitalized?

1) never
2) mostly never (even in the beginning of a sentence), except when used in
a title
3) usually never, except at the beginning of a sentence and in titles
4) capitalize when referring to the project, not capitalized when referring
to the package
5) usually capitalize like a proper noun except in code examples

Thoughts?
