It's a neccessity that the INI section naming be flexible.
E.g., I have intel-32 and intel-64 sections to test 32-bit
and 64-bit. Note, there's no way around this because the
Perl INI parser we're using does not allow duplicate section
names, and also, MTT constructs a scratch tree on the
assumption that each section has a unique name.

For "database text string regulation", there's also:

  http://svn.open-mpi.org/trac/mtt/ticket/7 (users should be
  able to delete or modify results from database)
