is there a way to handle different mimetype for same extension

[piaoger]

there are some extension has two mimetypes, such as：
rtf application/rtf; text/rtf
sh application/x-sh; text/x-sh

do we have a way to handle such a case or can we customize the buiitin mimetypes?

It'd be trivial to extend each function to return an array/slice of MIME types instead of a single one.

However, now we have the problem on how to order the types returned, assuming most people are just going to take the first type returned if they only need one. So the first type returned should be the most "correct", but what determines that is going to be inherently arbitrary.

As a rule of thumb I would tend to say whichever type was registered with the IANA first unless the later one explicitly supercedes the former, which means text/rtfwould actually come before application/rtf.

The new API I've proposed in this comment will support this: #43 (comment)
