Each host should have its own, local \fB/etc/cmcap\fR file. .PP Every machine running any Berkeley Plateau distributed continous media software needs to have a /etc/cmcap file. These /etc/cmcap files describe the continuous media capabilities of each machine and give other information about each machine. Each machine will have its own distinct /etc/cmcap file as /etc directories are not shared between machines. (e.g., the /etc/cmcap file for machine X will describe machine X only and will be different than the /etc/cmcap file for machine Y.) .PP The main effect of this Tcl script, when \fBsource\fR'd by a Tcl interpreter, is to fill the global associative array named \fIcmcap\fR with items concerning the capabilities of the host. .SH AUTHOR Brian Smith (bsmith@cs.berkeley.edu) .br Steve Yen (syen@cs.berkeley.edu)
