   2 ### Makefile used to three-stage build a tree of source code.  Also used to
   3 ### compile other bundles, first with cc, then with gcc.

  10 ### The first versions of the file were written by Rich Pixley (rich@cygnus.com).
  11 ### Many subsequent additions (and current maintainance by) david d `zoo' zuhn,
  12 ### (zoo@cygnus.com).
  13
  14 ### Every invocation of this Makefile needs to have a variable set (host),
  15 ### which is the named used for ./configure, and also the prefix for the
  16 ### various files and directories used in a three stage.

  27 ### START EDITTING HERE!!!
  28 ### These things will need to be set differently for each release.

  34 ### binaries should be installed into?

  36
  37 ### When working from a tagged set of source, this should be the tag.  If not,
  38 ### then set the macro to be empty.
  39 CVS_TAG :=
  40
  41 ### The name of the cvs module for this release.  The intersection of
  42 ### CVS_MODULE and CVS_TAG defines the source files in this release.
  43 CVS_MODULE := latest

  51 ### STOP EDITTING HERE!!!
  52 ### With luck, eventually, nothing else will need to be editted.
