+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes in patterns
+will always be interpreted as escape characters, not path separators.
+
+Note that `\` or `/` _will_ be interpreted as path separators in paths on
+Windows, and will match against `/` in glob expressions.
+
+So just always use `/` in patterns.
