+   on an Unixised setup:
+      run make tests
+   otherwise:
+       There is 3 standalone tools runtest.c runsuite.c testapi.c, which
+       should compile as part of the build or as any application would.
+       Launch them from this directory to get results, runtest checks 
+       the proper functionning of libxml2 main APIs while testapi does
+       a full coverage check. Report failures to the list.
