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