+=head1 NAME
+
+bibmradd.pl - add MR numbers to papers in a given bib file
+
+=head1 SYNOPSIS
+
+bibmradd [-d] [B<-f>] [B<-e> 1|0] [B<-o> I<output>] I<bib_file>
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-d>
+
+Debug mode
+
+=item B<-e>
+
+If 1 (default), add an empty mrnumber if a mr cannot be found. This
+prevents repeated searches for the same entries if you add new entries
+to the file. Calling C<-e 0> suppresses this behavior.
+
+
+=item B<-f>
+
+Force searching for MR numbers even if the entry already has one.
+
+=item B<-o> I<output>
+
+Output file. If this option is not used, the name for the
+output file is formed by adding C<_mr> to the input file
+
+=back
+
+=head1 DESCRIPTION
+
+The script reads a BibTeX file. It checks whether the entries have
+mrnumberss. If not, tries to contact internet to get the numbers. The
+result is a BibTeX file with the fields
+C<mrnumber=...> added.
+
+The name of the output file is either set by the B<-o> option or
+is derived by adding the suffix C<_mr> to the output file.
