%description

Elfutils is a collection of utilities, including stack (to show

backtraces), nm (for listing symbols from object files), size

(for listing the section sizes of an object or archive file),

strip (for discarding symbols), readelf (to see the raw ELF file

structures), elflint (to check for well-formed ELF files) and

elfcompress (to compress or decompress ELF sections).

%description debuginfod-client

The elfutils-debuginfod-client package contains shared libraries

dynamically loaded from -ldw, which use a debuginfod service

to look up debuginfo and associated data. Also includes a

command-line frontend.
