=head1 NAME

test2tasks.pl - Convert QTest logs into Qt Creator task files.

=head1 SYNOPSIS

    test2tasks.pl [OPTIONS] < logfile > taskfile

Options:

    -a              Use absolute file paths

    -r <some_path>  Prefix all file names by <some_path> (Used for
                    creating a summarized log of a submodule repository)


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.
