  $Log: DevFileHeader.h,v $
  Revision 1.3  1996/11/03 02:41:37  kmurli
  Modified to include the query schema level. Also modified to include DQL
  processing

  Revision 1.2  1996/08/23 16:56:15  wenger
  First version that allows the use of Dali to display images (more work
  needs to be done on this); changed DevStatus to a class to make it work
  better; various minor bug fixes.

  Revision 1.1  1996/07/11 17:25:40  wenger
  Devise now writes headers to some of the files it writes;
  DataSourceSegment class allows non-fixed data length with non-zero
  offset; GUI for editing schema files can deal with comment lines;
  added targets to top-level makefiles to allow more flexibility.
