  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.
  17
  18 ### The variable target may be set for the target of a cross-compilation.
  19
  20 ### The variable build may be to build a tree on a machine other than the host.

  32 ### These things will need to be set differently for each release.

  42 ### then set the macro to be empty.
  43 CVS_TAG :=
  44
  45 ### The name of the cvs module for this release.  The intersection of
  46 ### CVS_MODULE and CVS_TAG defines the source files in this release.
  47 CVS_MODULE := latest

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