+=head1 NAME
+
+bibdoiadd.pl - add DOI numbers to papers in a given bib file
+
+=head1 SYNOPSIS
+
+bibdoiadd [B<-c> I<config_file>] [B<-o> I<output>] I<bib_file>
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-c> I<config_file>
+
+Configuration file. If this file is absent, some defaults are used.
+See below for its format.
+
+
+=item B<-o> I<output>
+
+Output file. If this option is not used, the name for the
+output file is formed by adding C<_doi> to the input file
+
+=back
+
+=head1 DESCRIPTION
+
+The script reads a BibTeX file. It checks whether the entries have
+DOIs. If now, tries to contact http://www.crossref.org to get the
+corresponding DOI. The result is a BibTeX file with the fields
+C<doi=...> added.
+
+The name of the output file is either set by the B<-o> option or
+is derived by adding the suffix C<_doi> to the output file.
+
+There are two options for making queries with Crossref: free account
+and paid membership. In the first case you still must register with
+Crossref and are limited to a small number of queries, see the
+agreement at
+C<http://www.crossref.org/01company/free_services_agreement.html>. In
+the second case you have a username and password, and can use them for
+automatic queries. I am not sure whether the use of this script is
+allowed for the free account holders. Anyway if you try to add DOI
+to a large number of entries, you should register as a paid member.
+
+
+
+=head1 CONFIGURATION FILE
+
+The configuration file is mostly self-explanatory: it has comments
+(starting with C<#>) and assginments in the form
+
+ $field = value ;
+
+The important parameters are C<$mode> (C<'free'> or C<'paid'>,
+C<$email> (for free users) and C<$username> & C<$password> for paid
+members.
+
+
+=head1 EXAMPLES
+
+ bibdoiadd -c bibdoiadd.cfg citations.bib > result.bib
+ bibdoiadd -c bibdoiadd.cfg citations.bib -o result.bib

+ltx2crossrefxml.pl - a tool for creation of XML files for submitting to crossref.
+

+
+ltx2crossrefxml [B<-c> I<config_file>] [B<-o> I<output>] I<latex_file> I<latex_file> ...
+
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-c> I<config_file>
+
+Configuration file. If this file is absent, some defaults are used.
+See below for its format.
+
+
+=item B<-o> I<output>
+
+Output file. If this option is not used, the XML is output to stdout.
+
+=back
+
+=head1 DESCRIPTION
+
+The script takes a number of latex files and produces an XML file
+ready for submission to Crossref. Each file must be previously processed
+by LaTeX with the newest C<resphilosophica> package: the package creates
+the file C<.rti> wtih the information about the bibliography.
+
+The processing of reference list is at present rather limited: only so
+called unstructured references are produced.
+
+=head1 CONFIGURATION FILE FORMAT
+
+The configuration file is mostly self-explanatory: it has comments
+(starting with C<#>) and assginments in the form
+
+ $field = value ;
+
+=head1 EXAMPLES
+
+ ltx2crossrefxml.pl ../paper1/paper1.tex ../paper2/paper2.tex -o result.xml
