  * tidy up autoconfiguration of docbook stuff
  Ignore-this: 967773e506bb00fe19c08831fb4e03a6
  
   * use --nonet, so xmllint and co don't go off trying to download
     stuff from the web
  
   * use the http:// reference for the stylesheet, so we don't have to
     search the filesystem for it (should speedup ./configure)

    M ./aclocal.m4 -15 +12
    M ./configure.ac -3 +2
    M ./mk/config.mk.in -12 +11
    M ./rules/docbook.mk -1 +3
