Aditya's solution for the md5 stuff looked pretty smart, especially
since datestamp is not very reliable (it gives a compilation time
but says nothing about the revision that is used).

There is some useful stuff:

   print (status.luatex_version, type(status.luatex_version))
   print (status.luatex_revision, type(status.luatex_revision))
   print (status.banner, type(status.banner))

Gives:

   50      number
   0       string
   This is LuaTeX, Version beta-0.50.0-2010011912  string

Best wishes,
