 26dnl SHAVE_INIT([shavedir],[default_mode])
 27dnl
 28dnl shavedir: the directory where the shave scripts are, it defaults to
 29dnl           $(top_builddir)
 30dnl default_mode: (enable|disable) default shave mode.  This parameter
 31dnl               controls shave's behaviour when no option has been
 32dnl               given to configure.  It defaults to disable.
 33dnl
 34dnl * SHAVE_INIT should be called late in your configure.(ac|in) file (just
 35dnl   before AC_CONFIG_FILE/AC_OUTPUT is perfect.  This macro rewrites CC and
 36dnl   LIBTOOL, you don't want the configure tests to have these variables
 37dnl   re-defined.
 38dnl * This macro requires GNU make's -s option.
