#Usage: fsgs2bnetd "source directory" "destination directory"
#source directory:    directory contains fsgs account files 
#destnation directory: directory to save newly created bnetd 
#                      accounts,should exist before run this 
# 
#there is another change made to bnetd account in this script 
#i think fsgs account filename format <username> is better 
#than using bnetd's <userid>, so i kept it in fsgs format. 
#you may change it by edit the script yourself
