IC has a multitude of command-line switches that allow control of a
number of things. Explanations for these switches can be gotten by issuing
the command "ic -help".
IC stores the search path for and name of the library files
internally; theses may be changed by executing the command "ic
-config". When this command is run, IC will prompt for a
new path and library file name, and will create a new executable copy
of itself with these changes.
