+.Sh NAME
+.Nm elfdump
+.Nd "display information about"
+.Tn ELF
+files
+.Sh SYNOPSIS
+.Nm
+.Fl a | cdeGhiknprsv
+.Op Fl S
+.Op Fl V
+.Op Fl N Ar name
+.Op Fl w Ar file
+.Ar file ...
+.Sh DESCRIPTION
+The
+.Nm
+utility
+dumps various information about the specified
+.Tn ELF
+.Ar file .
+.Pp
+The options are as follows:
+.Bl -tag -width ".Fl w Ar file"
+.It Fl a
+Dump all information.
+.It Fl c
+Dump shared headers.
+.It Fl d
+Dump dynamic symbols.
+.It Fl e
+Dump ELF header.
+.It Fl G
+Dump the GOT.
+.It Fl h
+Dump the hash values.
+.It Fl i
+Dump the dynamic interpreter.
+.It Fl k
+Dump the ELF checksum.
+.It Fl n
+Dump note sections.
+.It Fl N Ar name
+Only dump the section with the specific
+.Ar name .
+Archive symbol table can be specified with
+the special section name ARSYM.
+More than one
+.Fl N
+option may appear.
+.It Fl p
+Dump the program header.
+.It Fl r
+Dump relocations.
+.It Fl s
+Dump the symbol table.
+.It Fl S
+Output in the Solaris
+.Nm
+format.
+.It Fl v
+Dump the symbol-versioning sections.
+.It Fl V
+Print a version identifier and exit.
+.It Fl w Ar file
+Write output to a
+.Ar file
+instead of the standard output.
+.El
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+The following is an example of a typical usage
+of the
+.Nm
+command:
+.Pp
+.Dl "elfdump -a -w output /bin/ls"
+.Pp
+To dump the content of '.dynsym' symbol table:
+.Pp
+.Dl "elfdump -s -N .dynsym /bin/ls"
+.Pp
+To dump the archive symbol table,
+but not the symbol tables of archive members:
+.Pp
+.Dl "elfdump -s -N ARSYM /usr/lib/libelf.a"
+.Pp
+To dump the content of .got section and
+the symbol-versioning sections in Solaris
+.Nm
+format:
+.Pp
+.Dl "elfdump -S -Gv /bin/ls"
+.Sh SEE ALSO
+.Xr objdump 1 ,
+.Xr readelf 1 ,
+.Xr elf 3

+.Re
+.Sh HISTORY
+The
+.Nm
+utility first appeared in
+.Fx 5.0 .
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+utility
+was written by
+.An Jake Burkholder Aq jake@FreeBSD.org .
+Later it was rewritten based on the
+libelf library.
+This
+manual page was written by
+.An David O'Brien Aq obrien@FreeBSD.org .
+.Pp
+.An Kai Wang Aq kaiw@FreeBSD.org
+rewrote it using the
+.Lb libelf
+and implemented additional functionality.
+.Sh BUGS
+Does not fully implement the
+.Tn ELF
+gABI.
