NAME
       append - Append to variable

SYNOPSIS
       append varName ?value value value ...?
_________________________________________________________________


DESCRIPTION
       Append all of the value arguments to the current value of variable
       varName.  If varName doesn't exist, it is given a value equal to the
       concatenation of all the value arguments.  This command provides an
       efficient way to build up long variables incrementally.  For example,
       ``append a $b'' is much more efficient than ``set a $a$b'' if $a is
       long.
