 The default is blank, but it can be changed as necessary.
+===== Other Devices =====
+Since ''prs'' bodies can have other two-terminal devices, the string to be used in the SPICE output for the device
+can be specified as:
+<code>
+string_table device "C"
+</code>
+This says the first device in the ''prs_device'' table is a capacitor (since ''C'' is the device string used by SPICE for capacitors).

 When production rules are automatically mapped to cells by the cell mapping pass, cell names are generated based on the production rule expressions for the pull-up and pull-down network. These names can get very long, and be difficult to read. This table is used to translate a generated name into something that is more understandable. The table should have an even number of entries that alternate between the generated name and the mapped name.
+<code>
+string cell_inport "in"
+string cell_outport "out"
+</code>
+When cells are generated, their ports are called ''in'' and ''out''. This can be changed to any port name using these configuration file options.
