# DescriptionBegin
#   Biblatex supports many author-year and numerical styles. It is mainly
#   aimed at the Humanities. It is highly customizable, fully localized
#   and provides many features that are not possible with BibTeX.
#   The use of 'biber' as bibliography processor is advised.

Requires biblatex

# The framework (biblatex|bibtex)
CiteFramework biblatex

# Cite style variants (default|authoryear|natbib)
# We provide both authoryear and numerical citations
CiteEngineType authoryear|numerical

# Default style files for either engine type
DefaultBiblio  authoryear:authoryear|numerical:numeric

# Maximum number of names before "et al." chimes in
MaxCiteNames 3


# The syntax of the cite command definitions below is:
# style@LyXName|alias*<!_stardesc!_stardesctooltip>[][]=latexcmd
# 
# * style:    A (comma-separated) list of citestyles to which
#             this command is specific. If preceeded by '!',
#             the list indicates citestyles for which the command
#             is _not_ supported.
# * 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.
#
# Style, 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, dropping
#   the '!' from the prefix (see below), e.g.:
#   _stardesc Starred command label
#   _stardesctooltip Tooltip for the starred command checkbox.
# * A trailing $ indicates that a command features "qualified citation
#   lists" (a specific Biblatex feature)
