======Synopsis:======
[[sendline]] <text>

======Description:======
The [[sendline]] command submits <text> to the command processor without
any further $-expansion (as contrasted with [[eval]])

If <text> begins with a slash ("/"), then <text> is taken to be a command.  
If <text> does not begin with a slash, then <text> is taken to be a message
that should be sent to the current window's current target.  

Ordinarily, when the user presses <enter>, that invokes the [[bind send_line]]
operation, which throws [[on input]].  Ordinarily, if you hook [[on input]],
then you must use [[sendline]] to submit the input line for processing.  If
you don't do this, then the user would be unable to do anything at the input
prompt!

======History:======
The [[sendline]] command first appeared in ircII.
