  NOTE: The acceptance tests currently work only for OS X, out of the box.
  On Linux, one has to manually configure the host visibility for the
  TLD _landrush-acceptance-test_. See *Linux* in the *Visibility on the Host* section of the link:Usage.adoc[Usage guide]. On Windows,

  ----
  $ bundle exec guard
  ----
  
  and your HTML documentation will be automatically updated on each change to an Asciidoc source file.
