+cvar_t variables are used to hold scalar or string variables that can
+be changed or displayed at the console or prog code as well as accessed
+directly in C code.
+
+it is sufficient to initialize a cvar_t with just the first two fields,
+or you can add a ,true flag for variables that you want saved to the
+configuration file when the game is quit:
+
+cvar_t	r_draworder = {"r_draworder","1"};
+cvar_t	scr_screensize = {"screensize","1",true};
+
+Cvars must be registered before use, or they will have a 0 value instead
+of the float interpretation of the string.
+Generally, all cvar_t declarations should be registered in the apropriate
+init function before any console commands are executed:
+
+host_framerate.inscribe();
+
+C code usually just references a cvar in place:
+if ( r_draworder.value )
+
+It could optionally ask for the value to be looked up for a string name:
+if (Cvar_VariableValue ("r_draworder"))
+
+Interpreted prog code can access cvars with the cvar(name) or
+cvar_set (name, value) internal functions:
+teamplay = cvar("teamplay");
+cvar_set ("registered", "1");
+
+The user can access cvars from the console in two ways:
+r_draworder		prints the current value
+r_draworder 0		sets the current value to 0
+
+Cvars are restricted from having the same names as commands to keep this
+interface from being ambiguous.
