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.
