  (% style="color: rgb(0,0,0);text-decoration: none;" %)Library cues are written like normal cues, they are also defined in a <cues> node, just with the difference that the XML tag is called library instead of cue:
--{{code language="xml"}}
--<library name="LibFoo" checktime="1h" checkinterval="5s">
--  <conditions>
--  [...]
--</library>
--{{/code}}
++{{code}}&lt;library┬áname=&quot;LibFoo&quot;┬áchecktime=&quot;1h&quot;┬ácheckinterval=&quot;5s&quot;&gt;┬á &lt;conditions&gt;┬á [...]&lt;/library&gt;{{/code}}
  (% style="color: rgb(0,0,0);text-decoration: none;" %)Although it is called library, itΓÇÖs basically just a cue that doesnΓÇÖt do anything. You can mix cues and libraries as you want, as root cues or sub-cues - the location within the file is unimportant. All that counts is the library name, which has to be unique within the MD script, like all other cue names.
  (% style="color: rgb(0,0,0);text-decoration: none;" %)To use a library, use the attribute ref:
--{{code language="xml"}}
--<cue name="Foo" ref="LibFoo"/>
--{{/code}}
++{{code}}&lt;cue┬áname=&quot;Foo&quot;┬áref=&quot;LibFoo&quot;/&gt;{{/code}}
  (% style="color: rgb(0,0,0);text-decoration: none;" %)This will create a cue with the name Foo that behaves just like the library cue LibFoo. In this example, LibFoo has to be a library in the same MD script file. To use a library LibFoo from another script, you have to qualify it with the script name, using the (%%)**(% style="color: rgb(0,0,0);text-decoration: none;" %)md(%%)**(% style="color: rgb(0,0,0);text-decoration: none;" %) prefix:
--{{code language="xml"}}
--<cue name="Foo" ref="md.ScriptName.LibFoo"/>
--{{/code}}
++{{code}}&lt;cue┬áname=&quot;Foo&quot;┬áref=&quot;md.ScriptName.LibFoo&quot;/&gt;{{/code}}
  (% style="color: rgb(0,0,0);text-decoration: none;" %)When the ref attribute is provided, all other attributes (except for name) will be ignored and taken from the library cue instead. ((% style="color: rgb(0,0,0);text-decoration: none;" %)By default a library creates its own namespace, as if namespace="static" were specified. See the section about namespaces.(%%))

  (% style="color: rgb(0,0,0);text-decoration: none;" %)In contrast to X3TC, a cue that references a library also has its own name (Foo in the example above), so other cues can access it in expressions by that name. Sub-cues of Foo cannot be accessed by their name though. Within the library itself, expressions can use all names of cues that belong to the library (the <library> and all sub-cues). They will be translated properly when the library is referenced. Examples:

--<cue name="Foo" ref="LibFoo"/>
--<cue name="Bar" ref="LibFoo"/>

  (% style="color: rgb(0,0,0);text-decoration: none;" %)If your library is supposed to provide a result to the library user, it is recommended to store a predefined variable in the library cue with a standardised name, e.g. $result. The user will be able to read it via CueName.$result. This variable does not have to be defined as a parameter but should be documented in the library.
