# This scripts work as following:
# (1) cp current xf86site.def (it may be created by imake-4 ports) 
#       to ${WRKDIR}/xc/config/cf.
#     this means this ports use imake-4's config defaultly.
# (2) Generate temporal config for compiling.
#     Some configs, such as `ForceNormalLib', `FreeBSDBuildXprog', are
#     used for compiling this ports localy. so these configs will be generated
#     this scripts. these configs will be stored to `host.def' file.
#     but this host.def will never install. use local only.
