  $Log: ApInit.h,v $
  Revision 1.5  1996/11/23 20:50:58  jussi
  Added declaration of DEVISE_MAX_TDATA_ATTRS (from Init.h).

  Revision 1.4  1996/10/07 22:53:41  wenger
  Added more error checking and better error messages in response to
  some of the problems uncovered by CS 737 students.

  Revision 1.3  1996/05/22 18:50:41  wenger
  Greatly simplified Init::DoInit() to only do what's necessary for
  attribute projection; other minor changes.

  Revision 1.2  1996/04/25 19:25:07  wenger
  Attribute projection code can now parse a schema, and create the
  corresponding TData object.

  Revision 1.1  1996/04/22 18:01:44  wenger
  First version of "attribute projection" code.  The parser (with
  the exception of instantiating any TData) compiles and runs.
