24 * This class represents a particular LyX "cite engine", which defines the features
25 * of a particular citation backend such as natbib or biblatex. In that sense, it is more like
26 * a LaTeX package, where a layout file corresponds to a LaTeX class.
28 * In general, a given cite engine can be used with any document class. That said,
29 * one cite engine may `require' another, or it may `exclude' some other cite engine.
30 * The requires and excludes are given in comments within the cite engine file,
31 * which must begin roughly so:
32 * # \DeclareLyXCiteEngine[natbib.sty]{Natbib}
34 * # Natbib supports a range of both author-year and numerical styles mainly
35 * # aimed at the Humanities. It features automatic sorting and merging of
36 * # numerical citations, annotations, capitalization of the `van' part of
37 * # author names, shortened and full author lists, and more.
39 * # Excludes: basic | jurabib
40 * The description will be used in the gui to give information to the user. The
41 * Requires and Excludes lines are read by the configuration script
42 * and written to a file citeengines.lst in the user configuration directory.
43 * That file is then read on startup to populate the CiteEnginesList, below.
45 * Engines can also be "provided" or "excluded" by document classes, using
46 * the ProvidesEngine and ExcludesEngine tags.
