+These are just simple test programs in which stripped down versions of the
+XPConnect invoke and stubs code can be built and tested as the code is brought
+up on various platforms. These probrams do not test the param sizing and copying
+functionality of the routines. However, they do supply a place where the lowest
+level assembly language code can be developed and debugged in the simplest of
+contexts before it is moved into the real routines. \ No newline at end of file
