- * util.php is a library of helper functions for common tasks such as
- * formatting bytes as a string or displaying a date in terms of how long ago
- * it was in human readable terms (E.g. 4 minutes ago). The library is entirely
- * contained within a single file and hosts no dependencies. The library is
- * designed to avoid any possible conflicts.
