modify Executable and Linkable Format (@dfn{ELF}) binary files, find and
handle Debugging With Arbitrary Record Formats (@dfn{DWARF}) debug data,
symbols, thread state and stacktraces for processes and core files on
GNU/Linux.  Elfutils includes @file{libelf} for manipulating ELF files,
@file{libdw} for inspecting DWARF data and process state and utilities like
@command{eu-stack} (to show backtraces), @command{eu-nm} (for listing symbols
from object files), @command{eu-size} (for listing the section sizes of an
object or archive file), @command{eu-strip} (for discarding symbols),
@command{eu-readelf} (to see the raw ELF file structures),
@command{eu-elflint} (to check for well-formed ELF files),
@command{eu-elfcompress} (to compress or decompress ELF sections), and more.")
