 Notes
 -----
-The UI layout is edited with wxFormBuilder.  The project file is
-uiproject.fbp.  It generates uibase.cpp and uibase.h, which define base
-classes that do the rote work of constructing all the UI elements.
-
 The release is built with GCC and then "strip bitcoin" to strip the debug
 symbols, which reduces the executable size by about 90%.
