libc6-lse: Dummy package.

 This package used to contain libraries optimized to support the "large
 system extensions", but such support is now contained in the base libraries
 in a way that works on all systems. This package is empty and can safely be
 removed.

libc6-pic: GNU C Library: PIC archive library

 Contains an archive library (ar file) composed of individual shared objects.
 This is used for creating a library which is a smaller subset of the
 standard libc shared library. The reduced library is used by debian-installer
 and may be useful for custom installation media and in embedded systems.

libc6-prof: GNU C Library: Shared Libraries

 Contains the standard libraries that are used by nearly all programs on
 the system. This package includes shared versions of the standard C library
 and the standard math library, as well as many others.
 .
 This package contains all libraries compiled for profiling.

libc6-s390: GNU C Library: 32bit Shared libraries for IBM zSeries

 Machine-readable data files, shared objects and programs used by the
 C library for localization (l10n) and internationalization (i18n) support.
 .
 This package contains tools to generate locale definitions from source
 files (included in this package). It allows you to customize which
 definitions actually get generated. This is a space-saver over how this
 package used to be, with all locales generated by default. This created
 a package that unpacked to an excess of 30 megs.

locales-all: GNU C Library: Precompiled locale data

 This package contains the precompiled locale data for all supported locales.
 A better alternative is to install the locales package and only select
 desired locales, but it can be useful on a low-memory machine because some
 locale files take a lot of memory to be compiled.

nscd: GNU C Library: Name Service Cache Daemon

 A daemon which handles passwd, group and host lookups
 for running programs and caches the results for the next
 query. You should install this package only if you use
 slow services like LDAP, NIS or NIS+.

nscd-dbgsym: debug symbols for nscd
