======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
