+Moved towards generic character mapping. Configuration file default.idx
+specifies character map files for register types w, p, u, etc.
+
+Implemented "begin variant" for the sgml.regx - filter.
+
+Fixed a few memory leaks.
+
+Added support for C++, headers uses extern "C" for public definitions.
+
+New filter grs.marc.<syntax> that reads MARC records in the ISO2709
+format. <syntax> refers to the abstract syntax.
+
Bug fix: The show records facility (-s) only displayed information for
the first record in a file (and not for every record in the file).
