Description:

The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function. The glibc package also contains
national language (locale) support and timezone databases.

This version of glibc has been heavily optimized and thus can be not as
reliable as standard version.
