   6 dnl shavedir: the directory where the shave scripts are, it defaults to
   7 dnl           $(top_builddir)
   8 dnl default_mode: (enable|disable) default shave mode.  This parameter
   9 dnl               controls shave's behaviour when no option has been
  10 dnl               given to configure.  It defaults to disable.
  11 dnl
  12 dnl * SHAVE_INIT should be called late in your configure.(ac|in) file (just
  13 dnl   before AC_CONFIG_FILE/AC_OUTPUT is perfect.  This macro rewrites CC and
  14 dnl   LIBTOOL, you don't want the configure tests to have these variables
  15 dnl   re-defined.
  16 dnl * This macro requires GNU make's -s option.
