+# Name:        wxPython.lib.rightalign
+# Purpose:     A class derived from wxTextCtrl that aligns the text
+#              on the right side of the control, (except when editing.)

+"""
+Some time ago, I asked about how to right-align
+wxTextCtrls. Answer was that it is not supported. I forgot it.
+
+Just a week ago, one of my clients asked me to have numbers right
+aligned. (Indeed it was that numbers MUST be right aligned).
+
+So the game begun. Hacking, hacking, ...
+
+At last, i succeed. Here is some code that someone may find
+useful. ubRightTextCtrl is right-aligned when you are not editing, but
+left-aligned if it has focus.
+
+Hope this can help someone, as much as this list helps me.
