cmml-timeshift: parses a CMML instance document and applies a timeshift to all the clip tags.
Usage: cmml-timeshift [options] filename Apply a timeshift to all the clip tags. Possible options: -s offset, --sec offset Specify the offset in seconds to add to clip tags -o filename, --output filename Specify the output filename. The file is written to standard output by default. -h, --help Display this help information -v, --version Display version information

main function of cmml-timeshift, which opens the CMML file, seeks to any given offsets, registers the callbacks, and then steps through the file in chunks of BUFSIZE size, during which the callbacks get activated as the relevant elements get parsed.
