- * Utility functions to make assertions about formats.

- * This module centralizes most of logic used when determining what algorithm
- * is most suitable (i.e., most efficient yet correct) for a given format.
- *
- * It might be possible to move some of these functions to u_format module,
- * but since tiny differences in the format my render it more/less
- * appropriate to a given algorithm it is impossible to make any long term
- * guarantee about the semantics of these functions.
