     ----cccc      Check for hierarchical compostion errors, this is
	     the default mode of operation.

     ----nnnn      Do not check for hierarchical compostion errors.

     ----ffff      Use 'booldata' from the current working directory as
	     input_file in which the layercombinations are speci-
	     fied instead of the standard one from the library.

     _N_b_o_o_l performs boolean operations on vln_files.  If no
     option or the "-c" option is given, the program also checks
     for hierarchical composition errors such as overlap of
     layers of different cells without the presence of terminals.
     Use the "-n" option to turn this mode of operation off.

     The boolean functions, which are performed, are specified in
     the file "booldata" in the directory
     "ICDPATH/lib/process/TECHN".  A boolean processing number,
     as specified in the file "booldata", is appended to the
     corresponding output file "bool_".

     If no cell_name is given the cells given in the file
     "exp_dat" are processed.

     The current working directory must be the project directory.

     The _n_b_o_o_l program is normally not called directly by the
     user, but it is used by the _d_i_m_c_h_e_c_k program.
