 % Changelog:
 %
 % 1.00 (2002/08/13) Initial release
 %
 % 1.10 (2002/09/27)
 %  1. Corrected minor bug for improperly formed warning message when a
 %     book was not given a title. Thanks to Ming Kin Lai for reporting this.
 %  2. Added support for CTLname_format_string and CTLname_latex_cmd fields
 %     in the BST control entry type.
 %
 % 1.11 (2003/04/02)
 %  1. Fixed bug with URLs containing underscores when using url.sty. Thanks
 %     to Ming Kin Lai for reporting this.
 %
 % 1.12 (2007/01/11)
 %  1. Fixed bug with unwanted comma before "et al." when an entry contained
 %     more than two author names. Thanks to Pallav Gupta for reporting this.
 %  2. Fixed bug with anomalous closing quote in tech reports that have a
 %     type, but without a number or address. Thanks to Mehrdad Mirreza for
 %     reporting this.
 %  3. Use braces in \providecommand in begin.bib to better support
 %     latex2html. TeX style length assignments OK with recent versions
 %     of latex2html - 1.71 (2002/2/1) or later is strongly recommended.
 %     Use of the language field still causes trouble with latex2html.
 %     Thanks to Federico Beffa for reporting this.
 %  4. Added IEEEtran.bst ID and version comment string to .bbl output.
 %  5. Provide a \BIBdecl hook that allows the user to execute commands
 %     just prior to the first entry.
 %  6. Use default urlstyle (is using url.sty) of "same" rather than rm to
 %     better work with a wider variety of bibliography styles.
 %  7. Changed month abbreviations from Sept., July and June to Sep., Jul.,
 %     and Jun., respectively, as IEEE now does. Thanks to Moritz Borgmann
 %     for reporting this.
 %  8. Control entry types should not be considered when calculating longest
 %     label width.
 %  9. Added alias www for electronic/online.
 % 10. Added CTLname_url_prefix control entry type.
 
 
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 %% DEFAULTS FOR THE CONTROLS OF THE BST STYLE %%
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
 % These are the defaults for the user adjustable controls. The values used
 % here can be overridden by the user via IEEEtranBSTCTL entry type.
 
 % NOTE: The recommended LaTeX command to invoke a control entry type is:
 % 
 %\makeatletter
 %\def\bstctlcite{\@ifnextchar[{\@bstctlcite}{\@bstctlcite[@auxout]}}
 %\def\@bstctlcite[#1]#2{\@bsphack
 %  \@for\@citeb:=#2\do{%
 %    \edef\@citeb{\expandafter\@firstofone\@citeb}%
 %    \if@filesw\immediate\write\csname #1\endcsname{\string\citation{\@citeb}}\fi}%
 %  \@esphack}
 %\makeatother
 %
 % It is called at the start of the document, before the first \cite, like:
 % \bstctlcite{IEEEexample:BSTcontrol}
 %
 % IEEEtran.cls V1.6 and later does provide this command.
 
 
 
 % #0 turns off the display of the number for articles.
 % #1 enables
 FUNCTION {default.is.use.number.for.article} { #1 }
 
 
 % #0 turns off the display of the paper and type fields in @inproceedings.
 % #1 enables
 FUNCTION {default.is.use.paper} { #1 }
 
 
 % #0 turns off the forced use of "et al."
 % #1 enables
 FUNCTION {default.is.forced.et.al} { #0 }
 
 % The maximum number of names that can be present beyond which an "et al."
 % usage is forced. Be sure that num.names.shown.with.forced.et.al (below)
 % is not greater than this value!
 % Note: There are many instances of references in IEEE journals which have
 % a very large number of authors as well as instances in which "et al." is
 % used profusely.
 FUNCTION {default.max.num.names.before.forced.et.al} { #10 }
 
 % The number of names that will be shown with a forced "et al.".
 % Must be less than or equal to max.num.names.before.forced.et.al
 FUNCTION {default.num.names.shown.with.forced.et.al} { #1 }
 
 
 % #0 turns off the alternate interword spacing for entries with URLs.
 % #1 enables
 FUNCTION {default.is.use.alt.interword.spacing} { #1 }
 
 % If alternate interword spacing for entries with URLs is enabled, this is
 % the interword spacing stretch factor that will be used. For example, the
 % default "4" here means that the interword spacing in entries with URLs can
 % stretch to four times normal. Does not have to be an integer. Note that
 % the value specified here can be overridden by the user in their LaTeX
 % code via a command such as: 
 % "\providecommand\BIBentryALTinterwordstretchfactor{1.5}" in addition to
 % that via the IEEEtranBSTCTL entry type.
 FUNCTION {default.ALTinterwordstretchfactor} { "4" }
 
 
 % #0 turns off the "dashification" of repeated (i.e., identical to those
 % of the previous entry) names. IEEE normally does this.
 % #1 enables
 FUNCTION {default.is.dash.repeated.names} { #1 }
 
 
 % The default name format control string.
 FUNCTION {default.name.format.string}{ "{f.~}{vv~}{ll}{, jj}" }
 
 
 % The default LaTeX font command for the names.
 FUNCTION {default.name.latex.cmd}{ "" }
 
 
 % The default URL prefix.
 FUNCTION {default.name.url.prefix}{ "[Online]. Available:" }
 
 
 % Other controls that cannot be accessed via IEEEtranBSTCTL entry type.
 
 % #0 turns off the terminal startup banner/completed message so as to
 % operate more quietly.
 % #1 enables
 FUNCTION {is.print.banners.to.terminal} { #1 }

 % This IEEEtran.bst features a very powerful and flexible mechanism for
 % controlling the capitalization, punctuation, spacing, quotation, and
 % newlines of the formatted entry fields. (Note: IEEEtran.bst does not need
 % or use the newline/newblock feature, but it has been implemented for
 % possible future use.) The output states of IEEEtran.bst consist of
 % multiple independent attributes and, as such, can be thought of as being
 % vectors, rather than the simple scalar values ("before.all", 
 % "mid.sentence", etc.) used in most other .bst files.
 % 
 % The more flexible and complex design used here was motivated in part by
 % IEEE's rather unusual bibliography style. For example, IEEE ends the
 % previous field item with a period and large space prior to the publisher
 % address; the @electronic entry types use periods as inter-item punctuation
 % rather than the commas used by the other entry types; and URLs are never
 % followed by periods even though they are the last item in the entry.
 % Although it is possible to accommodate these features with the conventional
 % output state system, the seemingly endless exceptions make for convoluted,
 % unreliable and difficult to maintain code.
 %
 % IEEEtran.bst's output state system can be easily understood via a simple
 % illustration of two most recently formatted entry fields (on the stack):
 %
 %               CURRENT_ITEM
 %               "PREVIOUS_ITEM
 %
 % which, in this example, is to eventually appear in the bibliography as:
 % 
 %               "PREVIOUS_ITEM," CURRENT_ITEM
 %
 % It is the job of the output routine to take the previous item off of the
 % stack (while leaving the current item at the top of the stack), apply its
 % trailing punctuation (including closing quote marks) and spacing, and then
 % to write the result to BibTeX's output buffer:
 % 
 %               "PREVIOUS_ITEM," 
 % 
 % Punctuation (and spacing) between items is often determined by both of the
 % items rather than just the first one. The presence of quotation marks
 % further complicates the situation because, in standard English, trailing
 % punctuation marks are supposed to be contained within the quotes.
 % 
 % IEEEtran.bst maintains two output state (aka "status") vectors which
 % correspond to the previous and current (aka "this") items. Each vector
 % consists of several independent attributes which track punctuation,
 % spacing, quotation, and newlines. Capitalization status is handled by a
 % separate scalar because the format routines, not the output routine,
 % handle capitalization and, therefore, there is no need to maintain the
 % capitalization attribute for both the "previous" and "this" items.
 % 
 % When a format routine adds a new item, it copies the current output status
 % vector to the previous output status vector and (usually) resets the
 % current (this) output status vector to a "standard status" vector. Using a
 % "standard status" vector in this way allows us to redefine what we mean by
 % "standard status" at the start of each entry handler and reuse the same
 % format routines under the various inter-item separation schemes. For
 % example, the standard status vector for the @book entry type may use
 % commas for item separators, while the @electronic type may use periods,
 % yet both entry handlers exploit many of the exact same format routines.
 % 
 % Because format routines have write access to the output status vector of
 % the previous item, they can override the punctuation choices of the
 % previous format routine! Therefore, it becomes trivial to implement rules
 % such as "Always use a period and a large space before the publisher." By
 % pushing the generation of the closing quote mark to the output routine, we
 % avoid all the problems caused by having to close a quote before having all
 % the information required to determine what the punctuation should be.
 %
 % The IEEEtran.bst output state system can easily be expanded if needed.
 % For instance, it is easy to add a "space.tie" attribute value if the
 % bibliography rules mandate that two items have to be joined with an
 % unbreakable space.
