 The cmake based buildsystem for expat works on Windows (cygwin, mingw, Visual
 Studio) and should work on all other platform cmake supports.
 
-Assuming ~/expat-2.2.9 is the source directory of expat, add a subdirectory
+Assuming ~/expat-2.2.10 is the source directory of expat, add a subdirectory
 build and change into that directory:
-~/expat-2.2.9$ mkdir build && cd build
-~/expat-2.2.9/build$
+~/expat-2.2.10$ mkdir build && cd build
+~/expat-2.2.10/build$
 
 From that directory, call cmake first, then call make, make test and
 make install in the usual way:
-~/expat-2.2.9/build$ cmake ..
+~/expat-2.2.10/build$ cmake ..
 -- The C compiler identification is GNU

+-- Build files have been written to: /home/patrick/expat-2.2.10/build
 
 If you want to specify the install location for your files, append
 -DCMAKE_INSTALL_PREFIX=/your/install/path to the cmake call.
