# description: \
# 	The Internet Software Consortium DHCP Server, dhcpd, implements \
# 	the Dynamic Host Configuration Protocol (DHCP) and the Internet \
# 	Bootstrap Protocol (BOOTP).  DHCP allows hosts on a TCP/IP network \
# 	to request and be assigned IP addresses, and also to discover \
# 	information about the network to which they are attached.  BOOTP \
# 	provides similar functionality, with certain restrictions.
