[-r] [-s] [-f [FEATURE1,FEATURE2]] [-h] filename [filename ...]
.SH DESCRIPTION
Read .note.dlopen notes from ELF files and report the contents.

ELF binaries store link-time dependencies in their headers, which can be parsed
by various tools. There is no machine-readable metadata about dependencies
loaded at build time via
.BR \%dlopen (3)
available by default. The ELF Dlopen Metadata specification aims to fill this
gap by defining a common format. See https://systemd.io/ELF_DLOPEN_METADATA/.

This tool allows parsing such a note, and printing out the result in various
formats.
