+# 2010-03-01 SJM Reading SCL record
+# 2010-03-01 SJM Added more record IDs for biff_dump & biff_count
+# 2008-02-10 SJM BIFF2 BLANK record
+# 2008-02-08 SJM Preparation for Excel 2.0 support
+# 2008-02-02 SJM Added suffixes (_B2, _B2_ONLY, etc) on record names for biff_dump & biff_count
+# 2007-12-04 SJM Added support for Excel 2.x (BIFF2) files.
+# 2007-09-08 SJM Avoid crash when zero-length Unicode string missing options byte.
