    Name        : glibc
    Product     : Fedora 33
    Version     : 2.32
    Release     : 3.fc33
    URL         : https://www.gnu.org/software/glibc/
    Summary     : The GNU libc libraries
    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.
