The code set registry files are on the Open Group ftp server.  Clients should
anonymous ftp to ftp.opengroup.org, then cd to pub/code_set_registry .  The
following files are there:

[ The latest release is 1.2g; the files from the previous release are also
present. The diff.* files show the incremental changes. ]

The file cs_registry1.2g is the commented source file.  Comments at the
beginning of the file describe the format of the body of the file.  The
suffix 1.2g indicates the revision number for the registry.  Whenever changes
are made to the registry, the file incorporating the changes will be given a
new revision number and added to the directory.

Requests for changes to the registry should be sent by email to
<cs-registry@opengroup.org>.

The shell script rgy_to_txt can be invoked with the revision number as its
single argument.  This shell script uses rgy_to_txt.awk to convert the
commented source file to a simplified format.  For instance, the command
"rgy_to_txt 1.2g" will read from the file cs_registry1.2g and write to
the file code_set_registry1.2g.txt, as was done above.
