   3 ## We keep a list of dependencies in `.depend' for each of the source
   4 ## files on which it depends.  When one of the source files is modified
   5 ## we remove its record from .depend and regenerate its dependencies,
   6 ## tacking them onto the end of .depend.  By including the .depend file
   7 ## into the makefile, we're telling make that the makefile depends on
   8 ## the dependency list in the .depend file.
   9 ##
  10 ## This is as fast as the `.d' method described in the GNU make manual
  11 ## for automatic dependencies, but has the added advantage that all
  12 ## dependencies are stored in one place.  The advantage over the
  13 ## `makedepend' program is that only those files that are out of date
  14 ## have dependency information rebuilt, and the Makefile is not
  15 ## modified.
  16 ##
  17 ## This is also where tracing information is updated.  The $(TRACE)
  18 ## program is run on each source file to make sure that the H5TRACE()
  19 ## macros are up to date.  If they are then the file is not modified,
  20 ## otherwise the file is changed and a backup is saved by appending a
  21 ## tilde to the file name.
