To make features.bbs, you can use the file, features.bbs as a guide. 
 
The format of the file is as follows:
LINE 1 ------------ruler
Line 2 - N              The actual programs that you make available to you
                        users.
 
Each line is broken up into fields. The fields are as follows:
Column 01 - 50         The full path name of the program plus commandline
Column   51            A space
Column 52 - 72         Description of program
Column   73            A space
Column 74 - 78         Privilege level assigned to the program
Column   79            An asterisk or space
 
If column 79 is an asterisk, '*', then the BBS software will switch back to
the default terminal parameters and then execute the program. After the 
program completes, it will then switch back to the BBS terminal parameters.
The user will be notified of the switching so that he/she can change his/her
terminal program if necessary.
 
If column 79 is a space, the BBS program will redirect stdout to a temporary
file and then send the output to the bbs user.
