This is the top level documentation file associated with the USNO-SA2.0
distribution.  Fortunately, it can be really simple.  USNO-SA2.0 is quite
similar to USNO-SA1.0, and if you are using the earlier version, all
you really need to do is substitute the new .ACC and .CAT files.

If you are new to USNO-SA, then you should start by reading READMESA.V10
which contains the READ.1ST file from that distribution.

The rest of the READ* files in this distribution come from the USNO-A2.0
distribution (and from USNO-A1.0), and provide extended documentation.

We are migrating Web sites, so please be patient during this transition.
The old site is
   http://www.usno.navy.mil/nofs
and the new site is
   http://www.nofs.navy.mil
Our intention is to provide the latest versions of the various READ* files
and other useful stuff on the PMM's page in the Web site, and to make the
long files available by FTP or CD-ROM.

If you wish to use USNO-SA for commercial applications or intend to
redistribute it, please check with us first.  This catalog contains
intellectual property rights claimed by many organizations (see README.V10)
and these must be respected.
