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