+Description
+===========
+
+This package implements a LaTeX command that converts an amsrefs
+bibliographical database (.ltb) to a BibTeX bibliographical database
+(.bib).
+
+The typical usage is to run LaTeX on a document such as
+
+\documentclass{article}
+\usepackage{ltb2bib}
+\begin{document}
+\writebib{bblsource}{bibdest}
+\end{document}
+
+This will convert the bibliographical entries in bblsource.ltb to
+BibTeX format, and write them to bibdest.bib.
+
+ltb2bib is the reverse of the "amsxport" option in amsrefs. Typical uses are:
+
+* produce bib entries for some publishers which don't accept amsrefs
+  (Taylor & Francis, for example);
+
+* import an ltb database in a database management program, e.g. for sorting;
+
+* access one's ltb database within emacs's RefTeX mode.

+%
+% \section{Introduction}
+%
+% The \textsf{amsrefs} package is a wonderful, pure-\LaTeX\
+% implementation of bibliographical databases. In a format close to
+% Bib\TeX's, one writes entries in database files (say
+% \verb+ltbsource.ltb+); \LaTeX\ extracts from these files the entries
+% required for the document (say \verb+myarticle.tex+), writes them to
+% myarticle.bbl and incorporates them in the document's bibliography
+% section. The file \verb+myarticle.bbl+ can be sent to the publisher
+% along with \verb+myarticle.tex+, or can be directly incorporated
+% into it.
+%
+% It happens, sometimes, that one needs the bibliographical entries in
+% Bib\TeX\ format:
+% \begin{itemize}
+% \item Some publishers (Taylor \& Francis, for example) refuse
+% to process \textsf{amsrefs} files, and require the authors to manually
+% retype them;
+% \item \textsf{amsrefs} cannot sort entries, so it may be useful to
+% convert a \textsf{amsrefs} database to Bib\TeX\ format to feed them to
+% bibliography management software;
+% \item \textsf{emacs}'s Ref\TeX\ mode, for example, requires the database
+% in Bib\TeX\ format.
+% \end{itemize}
+%
+% For these purposes, I have written this short \LaTeX\ package that
+% converts an \textsf{amsrefs} bibliography file to Bib\TeX.
+%
+% Note that the inverse operation, namely producing a \textsf{amsrefs}
+% bibliographical database out of a Bib\TeX\ one, is implemented by
+% the \verb+amsxport+ option of \textsf{amsrefs}.
+%
+% \section{Usage}
+%
+% The only command supplied by this package is \verb+\writebib+. It is
+% typically used in a driver-document \verb+doltb2bib.tex+ such as
+% the following:
+% \begin{verbatim}
+% \documentclass{article}
+% \usepackage{ltb2bib}
+% \begin{document}
+% \writebib{ltbsource}{bibdest}
+% \end{document}
+% \end{verbatim}
+% which, when invoked with `\verb+latex doltb2bib+', produces from
+% \verb+ltbsource.ltb+ the file \verb+bibdest.bib+.
+%
+% \DescribeMacro{\writebib}
+%
+% This command takes two arguments: an input and an output
+% filename. If the input filename is given without extension, then the
+% actual filename may have the extension \verb+.ltb+; and similarly
+% the output will be written to a file with the \verb+.bib+ extension
+% added.
+%
+% This command reads all \verb+\bib+ entries from the input file, and
+% writes corresponding Bib\TeX\ entries to the output file. It produces no
+% output.
