     One of the following options can be specified:

     ----gggg   The name of a graphics terminal.  The following graph-
	  ics terminals are supported:
	  apollo_15_color
	  hp2397
	  hp98700
	  hpgp
	  rast10

     ----dddd   The pathname of the graphics device.	Normally only
	  used in combination with the hpgp graphics device.

     ----xxxx   With this option, added for debugging purposes, a lot
	  of data about the x_compaction will be added to the
	  file 'stderr.file', or to stderr in case of Xdense.

     ----yyyy   With this option, added for debugging purposes, a lot
	  of data about the y_compaction will be added to the
	  file 'stderr.file', or to stderr in case of Xdense.

     ----ffff   If this option is chosen the technology_files
	  dense_data, dense_desr and dense_elmnts will be looked
	  for in the current working directory first and only if
	  not found there the standard ones will be taken from
	  the technology base.

     ----iiii   If this option is chosen the file specified will be
	  read and the dense_commands specified in it will be
	  carried out before control is handed to the user.

     If no -d and -g options are given the environment variable
     TERM is used to obtain the name of the graphics terminal.

     _D_e_n_s_e (DElft Network to Silicon Editor) is an edit program
     to transform a network via a stickdiagram into a layout.
     It must be started in a _p_r_o_j_e_c_t_d_i_r_e_c_t_o_r_y. It then adapts
     itself to the technology used in the project.  At the moment
     the nmos, the c5th and the c5tud technologies are installed.
     The program is menu driven with menus to edit the network,
     the stickdiagram and the layout.
     It reads/writes its data to the database in the CIRCUIT
     view.  The data describing a dense design are placed in the

     files NodDat, ConDat, ConstrDat, TermDat en InfDat of the
     design object.  Upon request the network of the design can
     be written to the standard files used for a network descrip-
     tion.  The layout description of the design can be written
     in the LAYOUT view of the database in the standard files,
     and/or it can be written to the current working directory in
     the form of a ldm_file.

     The editor is only fit for cells with Manhattan geometries.
     The network description only contains transistors and termi-
     nals and their connections. It does not contain resistors
     and capacitors.
