  $Log: DataSeg.c,v $
  Revision 1.2  1996/08/05 19:48:53  wenger
  Fixed compile errors caused by some of Kevin's recent changes; changed
  the attrproj stuff to make a .a file instead of a .o; added some more
  TData file writing stuff; misc. cleanup.

  Revision 1.1  1996/06/04 14:21:40  wenger
  Ascii data can now be read from session files (or other files
  where the data is only part of the file); added some assertions
  to check for pointer alignment in functions that rely on this;
  Makefile changes to make compiling with debugging easier.
