#      ipvsadm - IP Virtual Server ADMinistration program

#      Version: $Id$

#
#      This file:
#
#	ChangeLog - 
#
#	Wensong		:	Modified the Makefile and the spec files so
#				that rpms can be created with ipvsadm alone
#
#	P.Copeland	:	Modified the Makefile and the spec files so
#				that it is possible to create rpms on the fly
#				using 'make rpms'
#				Also added NAME, VERSION and RELEASE numbers to
#				the Makefile
#
#	Horms		:	Updated to add config_stream.c dynamic_array.c
#				Added autodetection of libpot
#			:	Added BUILD_ROOT support
#
#	Wensong		:	Changed the OBJS according to detection
#
#	Horms		:	Moved ipvsadm back into /sbin where it belongs
#				as it is more or less analogous to both route 
#				and ipchains both of which reside in /sbin.
#				Added rpm target whose only dependancy is 
#				the rpms target
#
#	P.Copeland	:	Added some casts to stop gcc grumbling.
#				Tried compiling with -pedantic to find any
#				oddities that should be fixed however -pedantic
#				*REALLY* hates popt though ipvsadm will compile
#				perfectly without popt.
#				Fixed the problem where ipvasdm.8 isn't wrapped
#				into the rpm because rpm tries to compress the
#				man page and then forgets to tell itself the new
#				name.
#				Minor changes, bumped the patch number up
#
