** This command performs actions associated with the /chat instance
** on the default remote Fossil repository (the Fossil repository whose
** URL shows when you run the "fossil remote" command) or to the URL
** specified by the --remote option.  If there is no default remote
** Fossil repository and the --remote option is omitted, then this
** command fails with an error.
**
** Subcommands:
**
** > fossil chat
**
**      When there is no SUBCOMMAND (when this command is simply "fossil chat")
**      the response is to bring up a web-browser window to the chatroom
**      on the default system web-browser.  You can accomplish the same by
**      typing the appropriate URL into the web-browser yourself.  This
**      command is merely a convenience for command-line oriented people.


**
** > fossil chat send [ARGUMENTS]
**
**      This command sends a new message to the chatroom.  The message
**      to be sent is determined by arguments as follows:

**        -m|--message TEXT      Text of the chat message
**        --remote URL           Send to this remote URL
**        --unsafe               Allow the use of unencrypted http://
**
** > fossil chat url
**
**      Show the default URL used to access the chat server.

** Additional subcommands may be added in the future.
