R3002   Can't open: '<file>'

     Explanation:  RMAKE was unable to open a make file specified on the
     command line, in the RMAKE environment variable, or in a #include
     directive.

     Action:  A full or partial path may be specified as part of any make
     filename in order to force RMAKE to look for the file in a particular
     drive and/or directory.  If no path is specified, RMAKE searches only
     the current directory.  The /S option causes RMAKE to search
     subdirectories as well.
