   parser for Python 2.x-3.x (previously, only 3.x was supported).

   timeplot. Eugene Kirpichov [10]announced timeplot, which is useful
   visualizing log files.

   Singapore FP Users Group First Meeting. Max Cantor [11]announced the
   first meeting of the Singapore FP Users Group, it will be Monday,
