function exptool(newfile,varargin)
%EXPTOOL - allow to create, modify, add, cut, .. segments of domain outline together
%
%   this routine is used to create, modify, cut,... an Argus file (.exp)
%
%   exptool(newprofile,'optionname',optionvalue)
%      creation of an argus file newprofile
%
%   Available options:
%      - include: include list of existing ARGUS files
%      - color: line color (default='r')
%      - selectioncolor: line color of selected profiles (default='b')
%      - linestyle (default='-')
%      - linewidth (default=0.2)
%      - marker (default='+')
%      - markersize (default=7)
%      - markeredgecolor (default='r')
%
%   Usage:
%      exptool(newfile,varargin)
%
%   Example:
%      exptool('domain.exp','include',{'domain1.exp' 'domain2.exp'},'color','g','marker','+')
