- %
- % Use the label instead of the number for citations, as if you had used
- % \bibitem[name]{name}..., but write the proper citation number to the aux
- % file. Ignore spaces before the \cite, inserting an ordinary interword
- % space. Also ignore spaces after commas in the input list. This package
- % is particularly useful for draft (draught) versions of documents that
- % will eventually use cite.sty or overcite.sty.
- %
- % This also keeps track of the order of first-citations in the text for
- % easy sorting (in lieu of BibTeX). To omit this counting...
- % in LaTeX 2.09: declare \nocitecount before the first \cite; or, for
- % a more permanent removal, comment-out the lines ending with %%o below,
- % and omit everything following the line that begins with %%o.
- % in LaTeX2e: specify \usepackage[nocitecount]{drftcite}, or perform the
- % editing described above.
- %
- % Drftcite keeps track of which references were cited, and issues warnings
- % for bibliography items that were never cited in the text.
- %
- % The characters <>|_{}\ are not present in the roman fonts, so if you use
- % them in identifiers, they will have to be typeset in typewriter style.
- % To do this,...
- % with LaTeX 2.09: un-comment two lines in the definition of \@citeverb.
- % with LaTeX2e: specify \usepackage[tt]{drftcite}
- %
- % `Citation...undefined' warnings are only given once per undefined
- % citation name. In the text, missing numbers are represented with a
- % bold `name?'. To restore multiple warnings...
- % for LaTex 2.09: edit: "delete this line to issue warnings always"
- % for LaTeX2e: specify \usepackage[verbose]{drftcite}
- %
- % This version of drftcite can co-exist with chapterbib.sty (version 1.4
- % or later).

- % [This file is named "drftcite" because "draftcite" is too long a name for

- %
- % Version 1991: Ignore spaces after commas in the parameter list. Create
- % \nocitecount to turn off counting the order of citations.
- % Version 3.1 (1992): protect \cite and \citen. (There is no version 3.0)
- % Version 3.2 (1993): Supress repetitions of warning messages. Include
- % \@extra@b@citeb hook for chapterbib.sty. Make \include handle case that
- % \cp@FOO was not defined.
- % Version 3.3 (1993): Fix \nocitecount. Change printing of undefined refs.
- % Version 3.4 (1994): LaTex2e support, including spaces in protected command
- % names; better chapterbib support.
