// bug 4573 - cimmof include file search path processing is inadequate
//
// Bug 4573 changed the behavior of the processing for locating specified
//  include files. The new procssing is based on the include file processing 
//  behaviour used by the C compiler.
//
//      The search path for included files previously was:
//          1. try to open the file in the current working directory.
//          2. process the include path array from the cimof(l) cmdline
//             processing which always include "dot" as a default search
//             path and then any paths specified on the command line 
//             with the -I option.
//
//      The search path for included files now is:
//          1. try to open the file in the same directory as the current
//             file being processed.
//          2. process the include path array from the cimof(l) cmdline
//             processing which only includes paths specified on the 
//             command line with the -I option.

  // Please reference PEP #43 for more information.

  // Note: Updating the class was not done when an "class already exists
  // exception" in cimmofParser::addClass() occurs because when it gets
  // to the catch the class has been fully populated (it has inherited
  // all the properties and qualifiers from the superclass).  This means
  // that the Version and Experimental qualifers were propagated to child
  // class.  This made checking whether a version or experimental change
  // would occur difficult. This class, cimmofParser::updateClass(), will
  // get the class, if it exists, from the repository and save off the
  // version and experimental qualifiers so that it can be compared with
  // qualifiers of the class in the mof files.  It it finds the class and
  // the class cannot be updated, cimmofParser::addClass() will be notified
  // that the class exists and send the same message that it has sent
  // in the past.  In cases when the class cannot be modified due to that
  // the allow experimental and allow version options have not be specified
  // then an appropriate message will also be sent to cimmofParser::addClass().

  // Note on Experimental qualifier:
  // With the implementation of PEP #43 Experimental classes cannot be
  // added to the repository unless the -aE option is specified in the
  // cimmof/cimmofl CLIs.

  // Note on Version qualifier:
  // Classes that cause a Major update (the m in m.n.u is changed) will
  // require that the -aV option be specified.  Classes that cause a
  // Down Revision will also require that the -aV option be specified.
  // If the version of the class in the mof file has the same version
  // as the class in the repository the class will not be updated.
  // Classes with the same version are considered the same.
  // The version specified in the Version qualifier will be checked for
  // a valid format.  A valid version format is m.n.u (m is major, n is minor,
  // and u is update).  Examples of valid version are 2, 2.7, 2.7.0
