function [] = pslaunch()
%PSLAUNCH    Launch Photoshop or attach to an already running Photoshop.
%   If Photoshop is already running, it will attach, otherwise it will 
%   launch Photoshop. This routine does not need to be called, as the 
%   library will do the above logic when you use any of the other Photoshop
%   routines.
%
%   Example:
%   pslaunch()
%
%   See also PSQUIT, PSJAVASCRIPT, PSCONFIG
