.Vb 4
\&  DBIx::Profile is a quick and easy, and mostly transparent, profiler
\&  for scripts using DBI.  It collects information on the query 
\&  level, and keeps track of first, failed, normal, and total amounts
\&  (count, wall clock, CPU time) for each function on the query.
\&
\&  NOTE: DBIx::Profile use Time::HiRes to clock the wall time and
\&  the old standby times() to clock the CPU time.  The CPU time is
\&  pretty coarse.
\&
\&  DBIx::Profile can also trace the execution of queries.  It will print 
\&  a timestamp and the query that was called.  This is optional, and 
\&  occurs only when the environment variable DBIXPROFILETRACE is set 
\&  to 1. (ex: (bash) export DBIXPROFILETRACE=1).
\&
\&  Not all DBI methods are profiled at this time.
\&  Except for replacing the existing "use" and "connect" statements,
\&  DBIx::Profile allows DBI functions to be called as usual on handles.
\&
\&  Prints information to STDERR, prefaced with the pid.
