+# XBM File handling
+#
+# History:
+# 1995-09-08 fl   Created
+# 1996-11-01 fl   Added save support
+# 1997-07-07 fl   Made header parser more tolerant
+# 1997-07-22 fl   Fixed yet another parser bug
+# 2001-02-17 fl   Use 're' instead of 'regex' (Python 2.1) (0.4)
+# 2001-05-13 fl   Added hotspot handling (based on code from Bernhard Herzog)
+# 2004-02-24 fl   Allow some whitespace before first #define
