libc6-dbg: GNU C Library: detached debugging symbols

 This package contains the detached debugging symbols for the GNU C
 library.

libc6-dev: GNU C Library: Development Libraries and Header Files

 Contains the symlinks, headers, and object files needed to compile
 and link programs which use the standard C library.

libc6-dev-amd64: GNU C Library: 64bit Development Libraries for AMD64

 which use the standard C library. This is the 64bit version of the
 library, meant for AMD64 systems.

 library.

libc6-dev-x32: GNU C Library: X32 ABI Development Libraries for AMD64

 Contains the symlinks and object files needed to compile and link programs
 which use the standard C library. This is the X32 ABI version of the
 library, meant for amd64 systems.

libc6-i386: GNU C Library: 32-bit shared libraries for AMD64

 This package includes shared versions of the standard C
 library and the standard math library, as well as many others.
 This is the 32bit version of the library, meant for AMD64 systems.

libc6-i386-dbgsym: debug symbols for libc6-i386
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-s390: GNU C Library: 32bit Shared libraries for IBM zSeries

 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 a minimal set of libraries needed for the Debian
 installer. Do not install it on a normal system.

libc6-x32: GNU C Library: X32 ABI Shared libraries for AMD64

 This package includes shared versions of the standard C library and 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.

multiarch-support: Transitional package to ensure multiarch compatibility

 This is a transitional package used to ensure multiarch support is present
 in ld.so before unpacking libraries to the multiarch directories. It can
 be removed once nothing on the system depends on it.

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
