See the NEWS file for information on what is new in this release of the specification. See the README for some general information about this specification.

This is an unofficial document produced by people not employed by MS without the permission or knowledge of MS. We hope that MS can see the value in this exercise and restrain their lawyers.

Every effort has been made to document each bit of the relevant formats and ensure that the documentation is accurate. However this effort is not yet complete and help is still needed to find meaning amongst the bits.

It is hoped that, in time, the documentation will be complete and, with luck, work may begin on the documentation of MS' other help systems.
