+Description: Micro Name Service Caching Daemon
+ A daemon which handles passwd, group and host lookups for running
+ programs and caches the results for the next query. You only need
+ this package if you are using slow Name Services like LDAP, NIS or
+ NIS+.
+ .
+ This particular NSCD is a complete rewrite of the GNU glibc nscd
+ which is a single threaded server process which offloads all NSS
+ lookups to worker children; cache hits are handled by the parent,
+ and only cache misses start worker children, making the parent immune
+ to resource leaks, hangs, and crashes in NSS libraries.
+ .
+ It should mostly be a drop-in replacement for existing installs using
+ nscd.
