-PROFILING WITH DBUG
-.R
-.P
-With
-.I dbug
-one can do profiling in a machine independent fashion,
-without a need for profiled version of system libraries.
-For this,
-.I dbug
-can write out a file
-called
-.B dbugmon.out
-(by default). This is an ascii file containing lines of the form:
-.DS CB N
-\fC<function-name> E <time-entered>
-<function-name> X <time-exited>
-.DE
-
-.P
-A second program (\fBanalyze\fR) reads this file, and produces a report on
-standard output.
-
-.P
-Profiling is enabled through the
-.B g
-flag. It can take a list of
-function names for which profiling is enabled. By default, it
-profiles all functions.
-
-.P
-The profile file is opened for appending. This
-is in order that one can run a program several times, and get the
-sum total of all the times, etc.
-
-.P
-An example of the report generated follows:
-.DS CB N

- Profile of Execution
- Execution times are in milliseconds

-As you can see, it's quite self-evident. The

-column is a
