      3 # If an include file is already installed, this always compares the
      4 # installed file to the one we are about to install. If they are the
      5 # same, it doesn't do the install. This is to avoid triggering massive
      6 # amounts of rebuilding.

     10 # includes:
     11 #	Installs the include files in BUILDDIR if we are using one, DESTDIR
     12 #	otherwise. This is to be run before `make depend' or `make'.
     13 #
     14 # install:
     15 #	Installs the include files in DESTDIR.
