 To choose the abbreviated (short) or unabbreviated (long) version of the
 bibliography strings, use one of these commands in your LaTeX file:
 
-    \bibliography{bibstring-abbrev,...,crossrefs-abbrevv}
+Most complete option. It will use full strings for journals
+(`bibstring-unabbrev`) and full proceedings info for conferences
+(`crossrefs`).
+
+     \bibliography{bibstring-unabbrev,...,crossrefs}
+
+No month and address option. It will use short strings for journals

-    \bibliography{bibstring-unabbrev,...,crossrefs}
+
+Abbreviations option. It will use short strings for journals

+info for conferences (e.g. Proceedings --> Proc., Conference -->
+Conf.) as in `crossrefs-abbrevv`. 
+
+    \bibliography{bibstring-abbrev,...,crossrefs-abbrevv}

+Super-compressed option. It will use short strings for journals

+'''This script was written by Alessandra Gorla to create a super
+abbreviated version of the crossref bibliography. Given
+crossrefs-abbrev.bib, which already excludes month and address, this
+script keeps only the acronyms of the conferences, which are assumed
+to be before the ":".
+
+Thus, "ICSE 2017: Proceedings of the International Conference ..."
+will be reduced to "ICSE 2017".

+If title and booktitle do not include any ":" the script keeps the
+strings as they are.
