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}
