Validates IDPF EPub Files
EpubCheck is a tool to validate IDPF Epub files. It can
detect many types of errors in Epub. OCF container
structure, OPF and OPS mark-up, and internal reference
consistency are checked. EpubCheck can be run as a
standalone command-line tool, installed as a web application
or used as a library.
