know when this left the tree, use 1300077 as the revision so we
avoid multiple bumps for the sparc64 removal.

.Sh NAME
.Nm elf2aout
.Nd "Convert ELF binary to a.out format"
.Sh SYNOPSIS
.Nm
.Op Fl o Ar outfile
.Ar infile
.Sh DESCRIPTION
The
.Nm
utility is used to convert an ELF formatted binary,
namely a kernel, to an a.out formatted one.
Most
.Tn OpenBoot
firmware require an a.out format or FCode boot image
and this utility is designed to accommodate.
If
.Ar infile
is not in ELF format, an error message will be presented.
.Sh DEPRECATION NOTICE
The
.Nm
utility is not present in
.Fx 13.0
and later.
.Sh SEE ALSO
.Xr elf 3 ,
.Xr a.out 5
.Sh HISTORY
