+======Synopsis:======
+$__rsubstr__(<substring> <search string>)
+======Technical:======
+The <substring> argument is a [[what is a word|dword]] which is unlike most
+other functions.
+This function searches for <substring> from the end of  <search string>
+and returns the $[[index]]() to it.
+======Practical:======
+They can be used to search for specific things in output from a server,
+or as an alternative to $match(*substring* searchstring).
+======Returns:======
+  * -1 if <substring> not found in <search string>
+  * index to <substring> in <search string> if found
+======History:======
+The $rsubstr() function first appeared in EPIC4pre1.016.
