+This allows cleaning the working tree by removing files that are not
+under version control.
+
+Normally, only files unknown to git are removed, but if the '-x'
+option is specified, ignored files are also removed. This can, for
+example, be useful to remove all build products.
+
 If any optional `<path>...` arguments are given, only those paths
 are affected.
