# The expected format of the MASTERS_FILE is one IP/host per line.

# character '#' as the first character of the line.  As an example, changing
# this MASTERS_FILE:
#
# 10.1.1.1
# 10.1.1.2
#
# to this one:
#
# 10.1.1.1
# #10.1.1.2
#
# removes the 10.1.1.2 IP address from being used.  Note that this does NOT
# support comments through the end of line, like this:
#
# 10.1.1.1  # my first IP
# 10.1.1.2  # my second IP
