+     "Performs brace expansions on strings.  Made popular by Unix shells, brace
+expansion allows users to concisely generate certain character vectors by taking
+a single string and (recursively) expanding the comma-separated lists and
+double-period-separated integer and character sequences enclosed within braces
+in that string.  The double-period-separated numeric integer expansion also
+supports padding the resulting numbers with zeros.")
