* wrap/python/spot.i: Include src/tgbalagos/dupexp.hh and
src/tgbalagos/stats.hh

ChangeLog

 2004-02-02  Alexandre Duret-Lutz  <adl@src.lip6.fr>
 
+	* src/tgbalagos/stats.hh, src/tgbalagos/stats.cc: New files.
+	* src/tgbalagos/Makefile.am: Add them.
+	* wrap/python/spot.i: Include src/tgbalagos/dupexp.hh and
+	src/tgbalagos/stats.hh
+
 	* src/tgbaalgos/ltl2tgba_fm.cc (ltl_to_tgba_fm): Identify states
 	with identical successors.  This optimizes the translation
 	of `a R (b R c)', for instance.
