+
+test2tasks.pl - Convert QTest logs into Qt Creator task files.
+
+=head1 SYNOPSIS
+
+    test2tasks.pl < logfile > taskfile
+
+The script needs to be run in the working directory from which the test log was
+obtained as it attempts to perform a mapping from the source file base names of
+the test log to relative path names by searching the files.
