echo "
We will now convert your existing uucp configuration to those required
by this implementation of Taylor uucp. This is not a destructive process.
Before existing files are overwritten, you will be given the opportunity
to save them to a tarred archive.

The conversion process consists of building new Taylor uucp configuration
files from the data in your existing files, saving your old uucp files
to a tarred archive and finally copying the new files into place. The
conversion of the existing data files may have problems if you are performing
undocumented functions with the existing uucp facilities. For example,
if you have multiple entries for a single uucp site in L.sys, you may
not achieve the expected results with this conversion. If you run special
shell scripts to swap L-devices with other files, which some COHERENT users
have done in order to use multiple modems on their systems, this conversion
process will only deal with the existing L-devices file. This means that the
data from the other files used to swap with L-devices will not be accounted
for.

If, while running the conversion process you notice messages that indicate
potential problems, write them down. If necessary, you can always re-run this
script (/conf/upd2tay.post).

Now for the tricky part. This implementation of Taylor uucp does not use
the files /usr/lib/uucp/L.sys nor /usr/lib/uucp/Permissions. Instead, the
contents of the 2 files are merged into the single file /usr/lib/uucp/sys.

This conversion process makes several assumptions. Please read them
carefully.

	1) In the Permissions file, if you have specified NOWRITE and 
	   NOREAD parameters, they follow the READ and WRITE parameters.

	2) There is only 1 ACU entry in /usr/lib/uucp/L-devices.

	3) If an L.sys entry occupies more than 1 line, the line
	   continuation character (backslash) is followed immediately 
	   by a newline.

	4) A single L.sys entry occupies no more than 2 lines.

If you want to check your existing uucp configuration files against the
items just listed, you may abort the update process now with <ctrl><c>.

This is your ONLY chance to save your existing UUCP programs that would

Important note: The manner in which Taylor uucp handles dialing via a
modem is vastly different from COHERENT uucp's method. Instead of relying
upon data in /etc/modemcap, Taylor uucp literally 'chats' with the modem
to set register values and to dial. When a connection has ended, Taylor
uucp can be configured to chat with the modem again to set registers or
perform other functions.

Because of this, you may encounter difficulty getting Taylor to dial out
during your initial attempts to use it. Please refer to the UUCP articles
in your new COHERENT manual for making dial file entries.
