To add new command, do the following (BASICALLY)..

Go in srcfiles/command_funcs.c

1. In the sys[]. commands structure where all the commands are defined,
   add a line for your command, in the following form..
   {"NAME", LEVEL, JUMP_LEVEL, TYPE, "ABBREVIAITON"},
   NAME        : The name of the command
   LEVEL       : The lowest level that can use the command
   JUMP_LEVEL  : A unique number for the command. This is the next highest 
                 number not used in sys[].
   TYPE        : The type of command for .h categorization. Types are listed
                 in constants.h
   ABBREVIATION: The single character abbreviation given to the command by 
                 default. Users cna change theirs with .abbrs

 Example: {".newcmd",   0,   200, NONE, ""},


2. In the exec_com() function add a case: for your command just like the
   rest of the commands. The format is:
   case JUMP_LEVEL: FUNCTION_NAME; break; /* short command comment */

Example: case 200: newcmd(user,inpstr);  break;  /* a test command */


3. Add your function in the code where the other commands are defined.
   (So as to tell the program what you want the command to do.)

   Example:
    newcmd(user,inpstr)
    int user;
    char *inpstr;
    {

    }


4. Re-compile the talker
