that's really nice to hear! :)

Regarding without GUIs: Since my last patch (which was pushed by Jordi
recently), there's a function 'profshow' which can be used to print out
the "hottest" functions in a table.

Maybe you already used this function and don't regard it as a real
"GUI", but at least you don't have to work through the structure array
any longer and get the data already sorted.

Daniel,

Just want to add my congratulations.  I  gave profile a first
try:  worked perfectly!  I do not know if profshow is a "GUI" but it
seems it will work just fine for me.  Do not worry about GUIness
just keep making stuff that works.

You seem to have gotten a lot done this Summer already.
Google should be impressed, too.
