   Parts of queries can be lifted into `library files <https://help.semmle.com/QL/ql-handbook/modules.html#library-modules>`__ with the extension ``.qll``. Definitions within such libraries can be brought into scope using “import” statements, and similarly QLL files can import each other’s definitions using “import” statements.
 
   Logic can be encapsulated as user-defined `predicates <https://help.semmle.com/QL/ql-handbook/predicates.html>`__ and `classes <https://help.semmle.com/QL/ql-handbook/types.html#classes>`__, and organized into `modules <https://help.semmle.com/QL/ql-handbook/modules.html>`__. Each QLL file implicitly defines a module, but QL and QLL files can also contain explicit module definitions, as we will see later.

   Queries are written in `QL <https://semmle.com/ql>`__ and usually depend on one or more of the `standard CodeQL libraries <https://github.com/semmle/ql>`__ (and of course you can write your own custom libraries). They are compiled into an efficiently executable format by the QL compiler and then run on a CodeQL database by the QL evaluator, either on a remote worker machine or locally on a developer’s machine.
 
-  Query results can be interpreted and presented in a variety of ways, including displaying them in an `IDE plugin <https://lgtm.com/help/lgtm/running-queries-ide>`__ such as QL for Eclipse, or in a web dashboard as on `LGTM <https://lgtm.com/help/lgtm/about-lgtm>`__.
