# 01z,15sep10,xhs  support IPLITE
# 01y,05feb10,mry  Add ipmacsec lib
# 01x,11jun09,dwb  Adding vxdot1x
# 01w,16dec08,mry  Add wps lib
# 01v,25mar09,pee  WIND00160969
# 01u,11feb09,ggz  Move coreip and bridge into CVS
# 01u,03dec08,f_g  Added ipsctp to IP_LIB_BASE_NAMES.
# 01t,25aug08,pee  adding to the list.
# 01t,25aug08,pee  adding files to inet6 list.
# 01s,30jun08,mze  allow -inet6only as a OPT and removed the -fr variations
# 01r,30may08,dlk  Added vxmux to IP_LIB_BASE_NAMES.
# 01q,29oct07,mry  Merging ipsupp/ipeap changes
# 01p,10sep07,mry  Add 8021x lib
# 01o,05oct07,pee  adding INET / INET6 definition and caching. Moved from
#                  ipcom.
# 01n,20sep07,pee  WIND00105231
# 01m,01jun06,tkf  Add netcommon, netapps, and netwrap to IP_LIB_BASE_NAMES.
# 01l,26dec06,tkf  Define IPBASIC for bootrom* targets (as workaround for
#                  CQ84418).
# 01k,14dec06,tkf  Define IPBASIC if OPT==-basic.
# 01j,13dec06,tkf  Added OPT=-basic option.
# 01k,17oct06,kch  Removed unsupported directories from IP_LIB_BASE_NAMES.
#                  Also added ipradius to IP_LIB_BASE_NAMES.
# 01j,22sep06,dlk  Add interpeak stack support. Remove virtual stack OPTS.
# 01i,09jan06,kch  Include firewall to the -inet6 build option for MSP.
# 01h,15apr05,kch  Changed 'inet6_fr' to '-inet6_fr' and 'inet6_vs_fr'
#                  to '-inet6_vs_fr'.
# 01g,14apr05,kch  Fixed SUPPORTED_OPTIONS such that virtual stack build 
#                  options will be supported for MSP only. Added ROUTER_STACK 
#                  setting to virtual stack option builds.
# 01f,31mar05,kch  Added the -vs, -vs_fr, -inet6_vs and inet6_vs_fr build 
#                  options for virtual stack.
# 01e,23sep04,dlk  Use OPT_DEFINE instead of EXTRA_DEFINE. Using
#                  EXTRA_DEFINE requires 'override', which breaks later
#                  additions to EXTRA_DEFINE (e.g. in some BSPs) which
#                  don't use 'override'.
# 01d,02sep04,dlk  Remove dsi from -inet6 builds. Tighten check
#                  on OPT validity. Add aim to free build libraries.
#		   Do not modify ADDED_CFLAGS.
# 01c,04may04,dlk  Added the -inet6_fr build option. Remove references
#                  to the fpio library.
# 01b,20apr04,dlk  Added -inet6 build option.
# 01a,04feb04,dlk  written.
