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.
