I have a question about the fields that are printed out by ACL 4.3.2 
(prof:show-flat-profile) command.  In particular, what do the "self secs" 
and "total secs" columns present, and how is it different from the "% Time" 
columns?  

I enclose an example of a profile below.  I have looked in the user manual,
pp 11-13 
to pp 11-15, but it doesn't really say anything about this. 

> (prof:show-flat-profile)

Sample represents 99.2 seconds of processor time (out of a total of 99.2)

Times below 1.0% will be suppressed.

Thanks in advance for any hints,
