SUMMARY = "Library containing NIS functions using TI-RPC (IPv6 enabled)"
DESCRIPTION = "This library contains the public client interface for NIS(YP) and NIS+ \
               it was part of glibc and now is standalone packages. it also supports IPv6. \
               This recipe should work for extracting either the glibc or standalone libnsl \
               from the external toolchain."
