+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.
