Subject: refer -> BiBTeX conversion

Following feedback from a number of users, in particular Johnathan
Bowen, I have modified and updated my 'ref2bib' script for conversion
of refer databases to BiBTeX format.

The files can now be extracted with a name of the user's choosing, to
avoid clashes with Johnathan Bowen's 'ref2bib', although that remains
the default.

The heuristics for assigning the type of reference have been augmented,
and a number of options are now selectable at run time, including the
length and number of authors to be used in generating keys.

Since the script is so long, it will probably be stored in the
appropriate archives, but I am happy to mail it to people who do not
have easy access to them.

X.SH NAME
Xprgrm \- convert refer input files to bibtex .bib files
X.SH SYNOPSIS
X.B prgrm
X[options ...] [files ...]
X.br
X.SH DESCRIPTION
X.B prgrm
Xreads the
X.I files
Xand produces a
X.B bibtex
Xreference list (a .bib file) on the standard output.
XIf no files are given, prgrm reads
Xstandard input.
X.PP
XA rudimentary attempt is made to convert
X.I troff
Xspecial characters and accents to the equivalent
X.I TeX
Xones.
XThe file ``prgrm.errs'' contains complaints about references that were
Xnot recognised, and other problems, as well as a summary of the
Xnumber of conversions completed.
X.PP
XSince
X.B refer
Xfiles are inherently unstructured (compared to
X.B bibtex )
X.B prgrm
Xonly does a passable job.  In particular
X.B refer
Xdoesn't require a keyword, while
X.B bibtex
Xdoes.
X.B prgrm
Xgenerates one using the following procedure:
Xthe first three characters of the last names of the first three authors
Xare concatenated, (preserving the capital letters), and the last two
Xdigits of the date are appended.  If this key has already been used,
Xthen 'a', 'b', 'c', are appended as needed.
XThere is an optional facility to start the key useage where it left off
Xin some previous conversion, by supplying a file containing the keys used.
X.PP
XJournal entries that appear to be in the standard bibliography style
Xfiles list of @strings, are converted.
XThe %D field is converted to month and year entries if there are two
Xfields, otherwise it is assumed to contain only the year.
XA large number of proper names, such as Hilbert, Turing, etc.,
Xwhich are often found in the titles of articles are enclosed in braces
X{} to protect them.  This treatment is also applied to any strings of
Xtwo or more consecutive capital letters, or to any isolated single
Xcapital letter (except A).
XThe user can supply an extra list of names to have their capitalisation
Xprotected.
X.PP
XTo determine the type of reference that the
X.B refer
Xentry is,
X.B prgrm
Xhas to do some ``calculated guessing''.  The heuristic used
Xhere (again, in order of precedence) is:
X.PP
X1. If it has a journal entry (%J) then it's considered to
Xbe an @article, unless there is a city entry (%C) or a publisher entry
X(%I) as well, in which case it's treated as an @inproceedings.
XIf there is no volume or number (%V or %N) entry it will be considered a
Xconference proceedings.
X.PP
X2. If it has a book entry (%B) then it's considered to
Xbe an @incollection.
X.PP
X3. If it has a report entry (%R) then it's considered to
Xbe a @techreport.
XIf the %R field contains the word ``Dissertation'' or ``Thesis'',
Xthe classification will be @phdthesis or @mastersthesis.
XIf the %R field contains the word ``Manual'' then it will be classified
Xas a @manual, and if it contains ``Unpublished''
Xit will be classified as a @unpublished.
X.PP
X4. If it has a issuer entry (%I) then it's considered to
Xbe a @book.
X.PP
X5. Otherwise it's considered to be a @misc, or @unpublished.
XAll these entries are listed in the ``prgrm.errs'' file.
XThe decision to classify it as @unpublished is made if the
Xword ``unpublished'' appears in the %O field.  This word is deleted.
X.PP
XQuite often
X.B prgrm
Xwill misguess and you will need to edit (by hand) the resulting .bib
Xfile.
X.PP
XAny fields that
X.B prgrm
Xdoesn't know about it will ignore (and complain about on stderr).
X.PP
XThe output is normally folded at word boundaries to ensure that
Xlines do not become too long on output.
XJournal entries that correspond to the abbreviations in the standard
Xbibliography styles are abbreviated, as are months mentioned in the date
Xfield.
X.PP
XNon blank lines that appear outside a reference are accumulated
Xand printed as a @comment section.  In fact BiBTeX would ignore them
Xas refer does, but identifying them separately seems cleaner, and might
Xmake prgrm suitable for converting refer bibliographies to scribe
Xformat.
X.SH OPTIONS
XThe following options are available:
X.TP 10
X.BI \- num
XSpecify a maximum width for the output.
XThe default is 72 characters.
XIf
X.I num
Xis omitted then lines are not folded and may be of any length.
X.TP 10
X.BI \-e " file"
XUse the next argument as the file name in which to print the errors
Xand summary of output.
X.TP 10
X.BI \-kf " file"
XUse the next argument as a file name to read the current state of key
Xusage from, and to save the key usage data at the end of the conversion.
XThis allows extra databases to be converted, without having to convert
Xall the old ones, and keeps the keys unique over all the databases.
X.TP 10
X.BI \-k " n"
XUse the next argument to decide how many authors names to use in generating the
Xkey. (Default 3).
X.TP 10
X.BI \-l " n"
XUse the next argument to decide how many charcters from each authors name
Xto use in generating the key. (Default 3).
X.TP 10
X.B \-n
XUse the name of the input file(s) to produce output file(s) with
Xthe same name and extension ``.bib'' rather than sending the output
Xto standard output.
X.TP 10
X.B \-u
XDisplay the usage of the command.
X.TP 10
X.B \-w
XDo not fold the output. Lines may be of any length.
X.SH ACKNOWLEDGMENT
XThis manual page is based on the manual page for
X.I r2bib ,
Xa program which performs a simpler version of the same conversion,
Xwritten by
XRusty Wright, Center For Music Experiment, University of California San
XDiego.
XThe options and their processing is based on the
X.I ref2bib
Xwritten independently by Jonathan Bowen of the Programming Research Group,
XOxford University.
XA number of the heuristics are also copied from Jonathan Bowen's
Xscript.
X.SH AUTHOR
XPeter King, Computer Science Department, Heriot-Watt University,
XEdinburgh.
X.SH BUGS
XImplemented as a
X.I sh(1)
Xscript, using
X.I sed(1)
Xand
X.I awk(1) .
XThis makes the conversion very slow, but also means that it is easily
Xmodified to alter the heuristics.  In particular, the key generation
Xalgorithm is easily changed.
X
XThe heuristics for identifying theses, unpublished papers, etc. are
Xrather crude.
