CLIG(1)			      Programmer's Manual		       CLIG(1)

NAME
       ::clig::Flag - declare a	flag (boolean, classic)	option

SYNOPSIS
       package require clig
       namespace import	::clig::*
       setSpec db

       Flag -opt varname usage

DESCRIPTION
       The Flag	command	declares an option without any parameters. The command
       line parser merely checks for the existence of opt on the command line.

   tcl
       If parseCmdline finds opt on the	command	line, variable varname in  the
       caller's	 context  is  set to 1.	If opt is not on the command line, the
       variable	is not set.

   C
       If opt is found on the command line the slot variableP in the structure
       returned	 by  the  parser will be set to	a non-zero value, otherwise it
       will be 0.

       Example use of Flag:

	 Flag -v verbose {verbose operation}
