# \DeclareLyXCiteEngine[natbib.sty]{Natbib (BibTeX)}
# DescriptionBegin
#   Natbib supports a range of both author-year and numerical styles mainly
#   aimed at the Humanities. It features automatic sorting and merging of
#   numerical citations, annotations, capitalization of the `van' part of
#   author names, shortened and full author lists, and more.

# The syntax of the cite command definitions below is:
# LyXName|alias*<!_stardesc!_stardesctooltip>[][]=latexcmd
# 
# * LyXName:  The LyX name as output in the LyX file. For
#             portability reasons, we try to use the same
#             name for same-formatted commands in the
#             different engines (thus many names stem from
#             natbib).
# * Alias:    A (comma-separated) list of commands that fall
#             back to the given LyX name in the current engine.
#             This is a bit like "ObsoletedBy" in the layouts.
# * latexcmd: The actual LaTeX command that is output.
#
# Alias and latexcmd are optional. If no latexcmd is given, the
# LyXName will be output to LaTeX.
#
# Note further:
#
# * The LyXName "keyonly" has a special meaning: only the citation key,
#   without any latex command, is output.
# * Capitalization indicates that the command also has a capitalized
#   form (\Latexcmd vs. \latexcmd). These usually enforce upcasing of
#   name prefixes (von Goethe => Von Goethe).
# * Brackets [] indicate the number of optional arguments (0, 1, 2).
# * The star * indicates there is a starred version of the command
#   (\latexcmd* vs. \latexcmd). By default, the starred version means:
#   Expand the author list even if the maxnames setting would cause
#   BibTeX/Biber to shorten it with "et al.".
#   If the star has a different meaning for a command, it can be
#   specified in angle brackets: <!_stardesc!_stardesctooltip>.
#   Maximal two translatable macro keywords, marked by the prefix '!_',
#   can be given. The first points to the string that replaces the
#   "Full aut&hor list" checkbox label in the Citation dialog, the
#   second one an optional tooltip for this checkbox. Note that these
#   two macros have to be defined in the CiteFormat section (see below),
#   dropping the '!' from the prefix (see below), e.g.:
#   _stardesc Starred command label
#   _stardesctooltip Tooltip for the starred command checkbox.

# CITE FORMAT
#

# The following defines how the commands are represented in the GUI
# (inset button and citation dialog) as well as in XHTML, docbook and
# plain text output.
#
# There are common definitions (default) and specific definitions for
# either cite engine type (which overwrite existing defaults.
#

# Input standard format definitions for the bibliography
Input stdciteformats.inc
