 native makefiles. You must have bakefile installed if you want to regenerate
 the makefiles. Bakefile currently runs on Unix and Windows systems. You will
 need Python >= 2.2 installed on Unix and either use Bakefile installer or have
 Python on Windows.
 
 Once you have installed Bakefile, you can easily regenerate the makefiles using
 native makefiles. You must have bakefile installed if you want to regenerate
 the makefiles. Bakefile currently runs on Unix and Windows systems. You will
 need Python >= 2.2 installed on Unix and either use Bakefile installer or have
 Python on Windows.
 
 Once you have installed Bakefile, you can easily regenerate the makefiles using

-the makefile in $(wx)/build/bakefiles directory. The makefile uses Unix make
-syntax and works on Unix or using either Borland Make or GNU Make (including
-native Win32 port called mingw32-make from http://www.mingw.org) on Windows.
-It is possible that other Windows make utilities work as well, but it wasn't
-tested. "make clean" only works on Unix or Cygwin or MSYS emulation layer on
-Windows.
-
-You can use following commands when generating the makefiles (must be run from
-$(wx)/build/bakefiles directory):
-
-make <filename>           generates one makefile (e.g. "make ../makefile.gcc")
-make all                  regenerates all makefiles that are out of date
-make library              only makefiles for the main library
-make <compiler>           only makefiles for given compiler; possible values
-                          are "borland", "watcom", "mingw", "autoconf", "msvc"
-                          and "mvsc6prj" (Visual C++ project files)
-make clean                deletes all generated files (Unix shell only)
+the bakefile_gen tool. Run it from $(wx)/build/bakefiles directory and it will
+regenerate all outdated makefiles. See $(wx)/build/bakefiles/README for more
+details.

 
 Note that it generates makefiles for samples and contrib libraries, too.
