======Synopsis:======
xdebug [<+|-><option>] [[block]]

======Description:======
This intentionally undocumented command provides access to developmental,
incomplete, broken, or debugging features.  These features are intended
for internal development use and are unsafe to use unless you are told 
otherwise.

The only complete documentation for this command is found in the source 
code, and maybe in https://www.epicsol.org/CHANGELOG if you're lucky.

If no arguments are specified, [[xdebug command|xdebug]] shows all of the 
xdebug options.

[[xdebug command|xdebug]] options are subject to change at any time and 
without any advance notice.

[[xdebug command|xdebug]] options can and probably will break your client.  
The use of [[xdebug command|xdebug]] results in expressly undefined behavior.  
You Have Been Warned.

The [[xdebug command|xdebug]] inbound and outbound options allow you to 
monitor the client's interaction with the server. This is potentially useful
for debugging scripts, and will probably not go away anytime soon.

The [[xdebug]] dword option allows you to turn on double quoted word support
which is experimental at this time, but will be officially supported soon.

The [[xdebug]] command optionally takes a [[block]] of code.  When you do 
this, the xdebug option is turned on, the block of code is executed, and
then **the original xdebug value is restored**.  This is a way to temporarily
ensure a value is turned on without having to save + restore the old value.

You cannot permanently turn on an xdebug option if you use the [[block]] form,
even if you do [[xdebug]] within the block, sorry.
