Name: Talker

Maintainer: Dan Greene, Creator: Paul Rovner

Date: April 20, 1984

Purpose: Talker is a simple tool for typescript-style communication between 2 or more Cedar users. It is included in the automatic 
bringover and in the prerun line of the standard user.profile.  Talker registers a "Talk" command with the UserExec.

Where to get it: [Indigo]<CedarX.X>Top>Talker.df


What it does:

The registered command "Talk <user name> <user name>...<user name> <CR>" establishes contact with each specified Talker user by 
creating an Icon in her Cedar world and flashing it (once every 6 seconds) until it is opened.  Communication is a line at a time; 
lines from other conversants are inserted while you are composing the next line to send to them.  After a Talker viewer is closed, 
it will not flash again until a new line arrives from one of the other conversants.  This can be used (for example) to leave a high 
priority message for someone.  Another conversant can be added to a conversation in progress by selecting the new conversant's name 
and hitting the JoinConversation menu item.

The default registry of the <user name> is chosen as follows:
        1)    The token after `Talk.DefaultRegistry:' in the user profile
        2)  The token after `Default.DefaultRegistry:' in the user profile
        3)  The user's own registry
