     _C_l_d_m adds the layout description of one or more cells
     (models in LDM) to the ICD database.  If a cell description
     is read, _c_l_d_m creates a new cell directory, and translates
     the LDM cell description into an internal database format.

     The cell descriptions are read from the specified LDM file
     and must be the last argument.  In most cases a file with
     suffix ".ldm".  The input must be conform the syntax rules
     of LDM.  If not, a syntax error will be the result, and an
     appropriate error message will be generated.

     To help you in making a correct cell definition you can
     invoke _c_l_d_m with option -s.  In that case _c_l_d_m performs only
     a syntax check, and two kinds of semantic checks, i.e.:

     1) a cell may not be redefined,

     2) a cell called in a cell description must already exist.

     Option -o is necessary when you don't want _c_l_d_m to translate
     the left beneath coordinate of a rotated and/or mirrored
     cell to the origin of its own frame of reference.

     If an error is detected the cell will not be added to the
     database.	This can result in subsequent error messages,
     complaining about the fact that the cell does not exist.
