+Globbing patterns are supported for specifying file paths:
+* `*` matches any number of characters, but not `/`
+* `?` matches a single character, but not `/`
+* `**` matches any number of characters, including `/`, as long as it's the only thing in a path part
+* `{}` allows for a comma-separated list of "or" expressions
+* `!` at the beginning of a pattern will negate the match
+
