Tcl/Tk front-end for gprof (profiler)
(Version 1.1)

Main Window (left):
a) name of a function, routine, method, ...
b) percentage of the overall time consumed by a) (including all sub-routines)
c) time consumed by function a) (including all sub-routines)
d) time consumed by the sub-routines of a)only (including their sub-sub-routines...)
e) number of (non-recursive) calls to function a) (eventually: "+ recursive calls" )
f) name of a caller of function a) (click on the name to go to the section for this caller)
g) time consumed by function a) when called by f)
h) time consumed by sub-routines of a) when a) was called by f)
i) number of calls to a)by f) / total number of calls to a)
j) name of a sub-routine called by a)(click on the name to go to the section for this sub-routine)
k) percentage of the time c) consumed by j)
l) time consumed by j) when called from a)
m) time consumed by the sub-routines of j) when j) was called by a)
n) number of calls to j) by a) / total number of calls to j)


profile.tcl shows the "call-graph profile" only (not the "flat profile") 
the column "time" shows the time consumed by a function including
all its sub-routines (i.e. columns self+children of the ascii-profile)

Fold / Unfold Sections:

Clicking on the  symbols or clicking with the right 
mouse-button on a function name folds / unfolds a section.
Follow a link and unfold the section of the target function :
click with the right mouse-button on the sub-routines / callers name

Colorization of ...

... "callers" depends on how often they called a function

... sub-routines depends on the percentage of time spend by a sub-routine

List of unfolded Functions (right):

Shows all functions with "unfolded" Sections in the main window (left). 
Click on a function name to go to that function. 
Clicking with the right mouse-button folds that section (list entry disappears).
You can hide/unhide the whole list by clicking on the  symbols in the right bottom corner
Tcl/Tk - wish (Unix / Linux / Windows) - tested with tcl/tk-versions 8.3, 8.4
Compilation for profiling (with -pg option):
> cc -pg sourcecode.cpp -o executable
Running executable, which creates the file gmon.out:
> executable
Running gprof to create profile1.txt in ascii format:
> gprof executable gmon.out > profile1.txt
Starting front-end to display profile1.txt and optionally further profiles
> profile.tcl profile1.txt [profile2.txt ...]
Alternatively (if your version of wish isn't named "wish", but "wish8.4" or the like)
> wish8.4 profile.tcl profile1.txt [profile2.txt ...]
> gunzip profiler.tar.gz
"Install" (preferably in a directory containing no "profiler" subdirectory - see below):
> tar -xf profiler.tar
A directory "profiler" will be created containing these files:
