-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.
