[Bioclusters] Help needed for catch the time used by clustalw

For "rough and ready" measurements, the command you are looking for  
is "time":

      time -- time command execution

      time [-lp] utility

      The time utility executes and times utility.  After the utility  
      time writes the total time elapsed, the time consumed by system  
      and the time used to execute utility to the standard error  
stream.  Times
      are reported in seconds.

For example:

backdraft:~ cdwan$ time sleep 10

real    0m10.228s
user    0m0.001s
sys     0m0.007s

This means that my command "sleep 10" ran for 10.228 seconds of wall  
clock time, and that it used almost no actual system time.

There are more accurate and more complex ways of measuring execution  
time, but "time" works well, most of the time.
