-This package uses quilt to manage patches against the upstream source code.
+This package uses quilt to manage all modifications to the upstream
+source. Changes are stored in the source package as diffs in
+debian/patches and applied during the build.
-If you want to work on the package and are not familiar with quilt,
-please take a look at /usr/share/doc/quilt/README.source.
+See /usr/share/doc/quilt/README.source for a detailed explanation.
+
+The files ./src/java/net/sf/jabref/bst/BstLexer.java and
+./src/java/net/sf/jabref/bst/BstParser.java are generated with
+the command (also note that the Bst.g file is included in the patch
+debian/patches/05_antlrv32.patch):
+
+ antlr3 Bst.g
+
+After generation, they are hand-edited to contain the proper
+Java package name and to correct an issue with the _channel
+member field. The maintainers are working with upstream to
+either include the generation as part of the build process
+or to ship the upstream tarball with versions of the parser
+and lexer that operate with antlr 3.2.
