+======Synopsis:======
+$__substr__(<substring> <search string>)
+======Technical:======
+The <substring> argument is a [[what is a word|dword]] which is unlike most
+other functions.
+These functions search for <substring> in <search string> and return the
+index to it. $[[rsubstr]]() is identical to $__substr__(), except it searches from
+the end to the beginning.
+======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
