libace-tkreactor-dev 5.4.7-9 (powerpc binary) in ubuntu feisty

 Recognizing the need to write reactor-based GUI applications, the ACE
 community has created several reactor extensions for use with X Window
 System. Each of these extends the ACE_Select_Reactor to work with a
 specific toolkit. By using these reactors, your GUI application can remain
 single threaded yet still respond to both GUI events, such as button presses,
 any your own application events.
 .
 The ACE_TkReactor provides reactor functionality around the popular Tcl/Tk
 library. The underlying Tcl/Tk method used is Tcl_DoOneEvent().
 .
 This package contains development files.
