+the lowest memory location that will be used when your program or dll
+is loaded. To reduce the need to relocate and improve performance of
+your dlls, each should have a unique base address and not overlap any

+@c man begin DESCRIPTION elfedit
+
+@command{elfedit} updates the ELF header of ELF files which have
+the matching ELF machine and file types. The options control how and
+which fields in the ELF header should be updated.
+
+@var{elffile}@dots{} are the ELF files to be updated. 32-bit and
+64-bit ELF files are supported, as are archives containing ELF files.
+@c man end
+
+@c man begin OPTIONS elfedit
+
+The long and short forms of options, shown here as alternatives, are
+equivalent. At least one of the @option{--output-mach},
+@option{--output-type} and @option{--output-osabi} options must be given.
+
+@table @env
+
+@itemx --input-mach=@var{machine}
+Set the matching input ELF machine type to @var{machine}. If
+@option{--input-mach} isn't specified, it will match any ELF
+machine types.
+
+The supported ELF machine types are, @var{L1OM} and @var{x86-64}.
+
+@itemx --output-mach=@var{machine}
+Change the ELF machine type in the ELF header to @var{machine}. The
+supported ELF machine types are the same as @option{--input-mach}.
+
+@itemx --input-type=@var{type}
+Set the matching input ELF file type to @var{type}. If
+@option{--input-type} isn't specified, it will match any ELF file types.
+
+The supported ELF file types are, @var{rel}, @var{exec} and @var{dyn}.
+
+@itemx --output-type=@var{type}
+Change the ELF file type in the ELF header to @var{type}. The
+supported ELF types are the same as @option{--input-type}.
+
+@itemx --input-osabi=@var{osabi}
+Set the matching input ELF file OSABI to @var{osbi}. If
+@option{--input-osabi} isn't specified, it will match any ELF OSABIs.
+
+The supported ELF OSABIs are, @var{none}, @var{HPUX}, @var{NetBSD},
+@var{Linux}, @var{Hurd}, @var{Solaris}, @var{AIX}, @var{Irix},
+@var{FreeBSD}, @var{TRU64}, @var{Modesto}, @var{OpenBSD}, @var{OpenVMS},
+@var{NSK}, @var{AROS} and @var{FenixOS}.
+
+@itemx --output-osabi=@var{osabi}
+Change the ELF OSABI in the ELF header to @var{type}. The
+supported ELF OSABI are the same as @option{--input-osabi}.
+
+@item -v
+@itemx --version
+Display the version number of @command{elfedit}.
+
+@item -h
+@itemx --help
+Display the command line options understood by @command{elfedit}.
