## CHANGELOG:
## ====================
+## Version 1.2
+## 1. Converted docstrings to reST format, added doc for ePyDoc.
+## 2. Renamed helper functions, vars etc. not intended to be visible in public
+## interface to code.
+##
## Version 1.1
## 1. Added .SetFont() method that properly resizes control
## 2. Modified control to support construction via XRC mechanism.
