+Contains the 'dotdots' template, which, given a path, will output a set of
+directory traversals to get back to the source directory. Handles both '/' and
+'\' directory separators.
+
+Examples:
+  Input                           Output 
+    index.html                    ""
+    dir/index.html                "../"
+    dir/subdir/index.html         "../../"
+    dir//index.html              "../"
+    dir/                          "../"
+    dir//                         "../"
+    \some\windows\path            "../../"
+    \some\windows\path\           "../../../"
+    \Program Files\mydir          "../"
+
+Cannot handle ..'s in the path, so don't expect 'dir/subdir/../index.html' to
+work.
