+%% BibTeX bibliography style `splncs03'
+%%
+%% BibTeX bibliography style for use with numbered references in
+%% Springer Verlag's "Lecture Notes in Computer Science" series.
+%% (See Springer's documentation for llncs.cls for
+%% more details of the suggested reference format.)  Note that this
+%% file will not work for author-year style citations.
+%%
+%% Use \documentclass{llncs} and \bibliographystyle{splncs03}, and cite
+%% a reference with (e.g.) \cite{smith77} to get a "[1]" in the text.
+%%
+%% This file comes to you courtesy of Maurizio "Titto" Patrignani of
+%% Dipartimento di Informatica e Automazione Universita' Roma Tre

+%% ================================================================================================
+%% This was file `titto-lncs-02.bst' produced on Wed Apr 1, 2009
+%% Edited by hand by titto based on `titto-lncs-01.bst' (see below)
+%%
+%% CHANGES (with respect to titto-lncs-01.bst):
+%% - Removed the call to \urlprefix (thus no "URL" string is added to the output)
+%% ================================================================================================
+%% This was file `titto-lncs-01.bst' produced on Fri Aug 22, 2008
+%% Edited by hand by titto based on `titto.bst' (see below)
+%%
+%% CHANGES (with respect to titto.bst):
+%% - Removed the "capitalize" command for editors string "(eds.)" and "(ed.)"
+%% - Introduced the functions titto.bbl.pages and titto.bbl.page for journal pages (without "pp.")
+%% - Added a new.sentence command to separate with a dot booktitle and series in the inproceedings
+%% - Commented all new.block commands before urls and notes (to separate them with a comma)
+%% - Introduced the functions titto.bbl.volume for handling journal volumes (without "vol." label)
+%% - Used for editors the same name conventions used for authors (see function format.in.ed.booktitle)
+%% - Removed a \newblock to avoid long spaces between title and "In: ..."
+%% - Added function titto.space.prefix to add a space instead of "~" after the (removed) "vol." label
