+ *   slate_permutate's internal (weird) representation of a set of
+ *   weekdays.
+ *
+ * This function is intended to make it easy for one to take the
+ * output of an explode() call. For example, to decode $days_str =
+ * 'Monday, Tuesday, Friday', one would do
+ * school_crawl_days_format(explode(', ', $days_str));
+ *
+ * \param $days
+ *   An array of day names. These may be common abbreviations or
+ *   truncations (any truncations must be two chars long for
+ *   simplicity. One-char representations are supported, however, but
+ *   use 'm', 't', 'w', 'h', 'f' to distinguish thursday and
+ *   friday). Case does not matter.
+ * \return
+ *   slate_permutate's strange internal days representation.
