Clear and concise description of the problem

When writing exports, I want to exclude files based on regex or globs that shouldn't be exported.

Suggested solution

An exclude option under ExportOptions that takes an array of regexes or globs that will be honored

Alternative

Writing a custom exports fn, but that seems to be quite brittle.
