+# Files marked as export-ignore will be ignored from the release's
+# built via `git archive`. This simplifies the release script and 
+# uses an industry standard as opposed to possibly hard to read
+# shell scripts with many flags. Unfortunately, directories themselves
+# won't recursively ignore, so we need the top level directories
+# as well as their files.
