# HOWTO:
#
#   /load bitlbee_hide_password.pl
#
# When you're using Bitlbee and do either:
#
#    REGISTER <password>
#
# or:
#
#    IDENTIFY <password>
#
# Your password will be shown on screen, and more importantly logged
# in your logfiles. This extension intercepts these commands in your
# &bitlbee channel and hides it from screen & logs.
#
# Note: You can avoid the password going into the log without this
# plugin by doing:
#
#    IDENTIFY
#    /OPER
#
# But this script also makes sure that your REGISTER commands will be
# hidden, and of course "IDENTIFY <password>" commands if you ever
# forget to IDENTIFY with /OPER.
