# Subject: Nifty samba script
#
# Here is a really nifty script I just wrote for samba, it takes the wins
# database in /var/samba/wins and writes out two dns files for it. In this
# way network wide wins clients can get into the dns for use by unix
# machines.
# 
# Perhaps this could be included in  /usr/doc/examples or somesuch.
