+% 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.
