rcc--Remote cc cmd

The rcc command will work the same as the cc command, except that it navigates to a Topic in a remote Ark.

This command takes the same arguments as the cc command, except for an additional first argument which gives the hostname or hostname:port of the remote Ark.

Typical usage would be as a link embeded in text content:
{CommandHelphttp:/wiki/rcc/www.compstrm.org/ReadMe/CswCmd}

And yes, the rcc command will make use of single signon.
