+@chapter debuginfod
+@cindex separate debug files
+
+debuginfod is a web service that indexes ELF/DWARF debugging resources
+by build-id and serves them over HTTP.
+
+Binutils can be built with the debuginfod client library
+@code{libdebuginfod} using the @option{--with-debuginfod} configure option.
+This option is enabled by default if @code{libdebuginfod} is installed
+and found at configure time. This allows @command{objdump} and
+@command{readelf} to automatically query debuginfod servers for
+separate debug files when the files are otherwise not found.
+
+debuginfod is packaged with elfutils, starting with version 0.178.
+You can get the latest version from `https://sourceware.org/elfutils/'.
