   4 # Generate an h tree that includes the appropriate sys headers
   5 #
   6 # Usage: make_h_tree ${SRC} ...
   7 #
   8 # The source files in the specified directories will be scanned for include
   9 # directives. The h directory will be created under the current directory and
  10 # populated with stubs that include the actual header file for every header
  11 # included by any source file in the ${SRC} directories. Since this script is
  12 # for userspace only, this effectively just makes a file called h/foo.h that
  13 # contains:
  14 #    #include <sys/foo.h>
  15 # For every include directive that is found that looks like #include <h/foo.h>
  16 # This is an ugly hack to work around the naming of header files using h
  17 # instead of their proper names elsewhere in the code.
