The default ccm.ini file is located in $CCM_HOME/etc/ccm.ini. You can copy the default file to your home directory, and then modify it for your use. After you do this, the settings in your .ccm.ini file will override those of the system .ccm.ini file. Even if you haven’t changed any settings, if you don’t already have a personal .ccm.ini file, it is created automatically when you exit from your session.
You can create and edit your personal .ccm.ini file by using any text editor. The .ccm.ini file must reside in your home directory. Options that are preceded with the word Motif affect only the graphical user interface. When no interface is specified, the option applies to all interfaces, as appropriate.
