       FAKSPECTR is a module which allows one to create maps containing 
 artificial spectra.  If the file already exists, the new lines are 
 superposed on what is there, otherwise a new file is created with a
 size specified by the user.  The parameters for the spectra are input
 manually whereby the user enters the central location, the sigma of
 the gaussian, and the optical depth, if an absorption line, or the
 intensity, if an emission line.  A black body spectrum can also be
 input.
      In the future, one will be able to add smearing.  Allowance is
 made for the center of the line to be outside the boundaries of the map.
