+## add_trace.pl
+## Script to add a kdDebug() call as the first line of each method
+## including as many parameters as possible (i.e. those supported by kdDebug)
+## Very useful for tracing.
+##
+## Usage: perl -i add_trace.pl myfile.cpp
+##
+## Generates all statement with kdDebug(0) so that it is very easy
+## to remove them afterwards :
+## perl -pi -e 'if (/kdDebug\(0\)/) { $_ = ""; }' myfile.cpp
+## perl -pi -e 'if (/#include <kdebug.h> \/\/ inserted by add_trace/) { $_ = ""; }' myfile.cpp
+## 
+## needs perl 5.8+ for the Tie::File module
