   9  * Support for COMPUTE data sources (CDEF data sources). Removes the RPN
  10  * parser and calculator from rrd_graph and puts then in a new file,
  11  * rrd_rpncalc.c. Changes to core files rrd_create and rrd_update. Some
  12  * clean-up of aberrant behavior stuff, including a bug fix.
  13  * Documentation update (rrdcreate.pod, rrdupdate.pod). Change xml format.
