%%%                        In addition, date formatting supports a day

%%%                            month = {23~} # aug,
%%%                            month = aug # {~23},
%%%
%%%                        These older forms are, of course, still
%%%                        handled correctly.
%%%
%%%                        The UNIX C preprocessor can be used to
%%%                        extract the standard styles, as follows:
%%%
%%%                            cpp -P -DPLAIN xbtxbst.doc >plain.bst
%%%                            cpp -P -DUNSRT xbtxbst.doc >unsrt.bst
%%%                            cpp -P -DALPHA xbtxbst.doc >alpha.bst
%%%                            cpp -P -DABBRV xbtxbst.doc >abbrv.bst
%%%
%%%                        To obtain correct file header checksums, pipe
%%%                        the output through the checksum program, e.g.
%%%
%%%                            cpp -P -DPLAIN xbtxbst.doc | checksum >plain.bst
%%%
%%%                        The accompanying UNIX Makefile automates this
%%%                        job, and provides some extra leading comments
%%%                        in the generated style files warning the user
%%%                        not to modify them.
%%%
%%%                        Additional optional definitions are recognized
%%%                        to provide extensions to the standard styles:
%%%
%%%                            -D_CODEN for CODEN output
%%%
%%%                            -D_ISBN for ISBN output
%%%
%%%                            -D_ISSN for ISSN output
%%%
%%%                            -D_LCCN for LCCN output
%%%
%%%                            -D_PRICE for price output,
%%%
%%%                            -D_BOOKPAGES for book, techreport, manual,
%%%                            and thesis pages output.
%%%
%%%                            -D_URL to get World-Wide Web Uniform
%%%                            Resource Locator (URL) output.
%%%
%%%                            -D_NUMERIC_SUFFIXES to get numeric
%%%                            label suffixes -1, -2, ..., -26, instead of
%%%                            letters a, b, ..., z, so as to correctly
%%%                            handle alpha-style bibliographies with more
%%%                            than 26 entries for a single author in one
%%%                            year.  Change letter suffix code to switch
%%%                            to numeric suffixes if more than 26 letters
%%%                            are used, so that no matter which scheme is
%%%                            selected, correct output will always be
%%%                            obtained.
%%%
%%%                        The CODEN, ISBN, ISSN, LCCN, PRICE, and URL
%%%                        values are wrapped inside macros \showCODEN{}
%%%                        etc. that the user can provide alternate
%%%                        definitions of to change the formatting, or
%%%                        to suppress their output altogether.  That
%%%                        way, output identical to that of the four
%%%                        standard BibTeX style files can be obtained
%%%                        with these extended files, if these macros
%%%                        are defined to expand to empty strings.
%%%
%%%                        URL handling is slightly more complex,
%%%                        because URLs can contain characters which TeX
%%%                        must handle in verbatim mode in a typewriter
%%%                        font, and such text cannot readily appear
%%%                        inside nested macro arguments.  Consequently,
%%%                        URLs are formatted in the .bbl file like
%%%                        this:
%%%                            \ifshowURL {\showURL \path|...|} \fi
%%%                        where \showURL takes no argument, and
%%%                        normally expands to the 4-character string
%%%                        URL<space>.  The grouping braces ensure that
%%%                        any font changes made by \showURL remain
%%%                        localized.  Vertical bar is chosen as the
%%%                        verbatim path delimiter, because it cannot
%%%                        appear in URLs.  The other prohibited ISO
%%%                        Latin 1 characters are the non-printing
%%%                        control characters 0..31, plus those in the
%%%                        range 128..255, plus the ten special
%%%                        characters
%%%
%%%                            { } [ ] \ ^ ~ < > `
%%%
%%%                        See Internet RFC 1630 (June 1994) for more
%%%                        details.  (Backquote is not even mentioned
%%%                        there.)
%%%
%%%                        As an example of font changes, in LaTeX 2e
%%%                        you might define
%%%                            \newcommand{\showURL}{URL
%%%                                \let \oldtt = \tt
%%%                                \renewcommand{\tt}{\oldtt \itshape}}
%%%                        to get URLs set in a typewriter italic font.
%%%
%%%                        If desired, a sed script can be used to
%%%                        eliminate non-essential comments (this
%%%                        reduces the file size by 2/3); a command
%%%                        filter step like
%%%                                sed -e '/^%$/d' -e '/^%[^%].*$/d'
%%%                        will accomplish that job.
%%%
%%%                        The checksum field above contains a CRC-16
%%%                        checksum as the first value, followed by the
%%%                        equivalent of the standard UNIX wc (word
%%%                        count) utility output of lines, words, and
%%%                        characters.  This is produced by Robert
%%%                        Solovay's checksum utility."
%%%     }
%%% ====================================================================
%%% Revision history (reverse time order):
%%%
%%% 2.03 [15-May-1996]
%%%      Add CODEN support, ISBN and ISSN output for Article entries,
%%%      and ISBN output for TechReport entries (yes, these sometimes
%%%      do have ISBNs).
%%%
%%%      Add wrapper macros \showXYZ{} (XYZ = CODEN, ISBN, ISSN, LCCN,
%%%      PRICE, and URL) defined inside the thebibliography environment
%%%      to expand to XYZ (except for PRICE) and their arguments,
%%%      PROVIDED they are not already defined.  That way, the user can
%%%      provide alternate definitions outside the thebibliography
%%%      environment, for example, to suppress particular ones, or
%%%      to alter the font used.
%%%
%%%      Substantially revise leading comments to better document the
%%%      extensions.
%%%
%%% 2.02 [01-Apr-1996]
%%%	 Add day keyword support with new code in format.date function.
%%%	 Oren Patashnik will include this new keyword in standard styles
%%%	 in BibTeX 1.0.
%%%
%%%	 Add new function collapse.pagerange, and use it to collapse
%%%	 page ranges with identical initial and final numbers to a
%%%	 single number, so that bibliography files can distinguish
%%%	 between one-page documents, and documents missing final page
%%%	 numbers.
%%%
%%% 2.01 [25-Oct-1994]
%%%	 Add URL output support.
%%%
%%% 2.00 [12-Oct-1994]
%%%	 Add support for pages in theses and manuals, treating them
%%%	 like Book and InBook pages.
%%%
%%%	 Correct ISSN support: a typo caused output of ISBN instead of
%%%	 ISSN.
%%%
%%%	 Wherever ISBNs are output, also output an ISSN, if one
%%%	 exists, and vice versa.  The reason is that some periodicals
%%%	 (e.g. The X Resource, published by O'Reilly and Associates)
%%%	 have both ISSN and ISBN numbers, and can be purchased either
%%%	 as journal subscriptions, or as single volumes.
%%%
%%%	 For InProceedings and Proceedings output, issue a warning for
%%%	 a missing publisher: even though that field is optional, a
%%%	 bibliographic reference without it is incomplete.
%%%
%%%	 Remove harmless, but unneeded, single horizontal space before
%%%	 price output added with version 1.03.
%%%
%%%	 Change Proceedings and InProceedings to treat address values
%%%	 as publisher addresses, as they are with every other document
%%%	 type, rather than as conference addresses, which belong in
%%%	 the title field (that is how major libraries, including OCLC
%%%	 and Library of Congress, with nearly 60M holdings, represent
%%%	 them).  The need for this change has been discussed with
%%%	 BibTeX's author, Oren Patashnik, and there is a good
%%%	 possibility that BibTeX 1.0 will contain the change
%%%	 implemented here.  This is an INCOMPATIBLE change that will
%%%	 produce different .bbl file formatting.  However, the TUG and
%%%	 BibNet bibliography projects have consistently used address
%%%	 to me publisher/organization/institution address, and so
%%%	 already conform to the new practice.
%%%
%%% 1.05 [30-May-1994]
%%%	 Add NUMERIC_SUFFIXES support.
%%%
%%%	 Change all preprocessor statements to put else and endif
%%%	 labels inside C-style comments to conform to 1989 ISO/ANSI C
%%%	 Standard.
%%%
%%% 1.04 [11-Nov-1993]
%%%	 Add underscore prefix to new processor symbols to prevent
%%%	 substitution in comments
%%%
%%% 1.03 [11-Oct-1993]
%%%	 Add support for LCCN (Library of Congress Catalog Number)
%%%	 and price fields, and make ISBN, ISSN, LCCN, and price
%%%	 selectable by preprocessor conditionals.
%%%
%%% 1.02 [12-Sep-1991]
%%%      Merge in Barbara N. Beeton's suggestion for hyphen-less
%%%      line breaks around volume(number):page.
%%%
%%% 1.01 [10-Sep-1991]
%%%      Update file comment header and use Solovay checksum program.
%%%
%%% 1.00 [17-Oct-1990]
%%%      Original version merging hand-edits of is-xxx.bst files into
%%%      this master file, xbtxbst.doc.
