======Synopsis:======
[[set]] debug [<level>]

======Description:======
When turned on, this variable enables various degrees of debugging
while the client is running.  It is useful for seeing precisely where
a particular alias or function is failing, what variables are being
assigned what values, etc.  There are three general classes of debug
output, each assigned a unique number.

^ Bit ^ Value ^                      Purpose                         ^
|  0  |   1   | displays all commands executed, including aliases    |
|  1  |   2   | displays all actual alias and variable substitutions |
|  2  |   4   | displays all function calls and their return values  |

Multiple classes may be displayed at once by adding the desired
values together.  A setting of 0 (zero) turns off debugging.

======Examples:======
To show all commands executed and alias expansion:
	/set debug 3

To show everything:
	/set debug 7

======Other Notes:======
This command can generate a lot of output, so setting [[window hold_mode|HOLD_MODE]] on is
recommended.
