-.Sh SYNOPSIS
-.Nm elf2olf
-.Op Fl v
-.Op Fl o Ar opsys
-.Ar module ...
-.Nm olf2elf
-.Op Fl v
-.Ar
-.Sh DESCRIPTION
-The
-.Nm elf2olf
-utility reads the specified
-.Em ELF
-version 1 module operands and converts them to the default operating system's
-.Em OLF
-object module format.
-.Pp
-The
-.Nm olf2elf
-utility reverses the process.
-The
-.Ar module
-operands are processed in command line order.
-.Pp
-The options are as follows:
-.Bl -tag -width Ds
-.It Fl o Ar opsys
-Specifies the operating system
-.Em OLF
-tag
-.Em "opsys"
-as follows:
-.Pp
-.Bl -tag -width Ds -compact
-.It Ta Pa "openbsd" Ta "OpenBSD"
-.It Ta Pa "netbsd" Ta "NetBSD"
-.It Ta Pa "freebsd" Ta "FreeBSD"
-.It Ta Pa "44bsd" Ta "4.4BSD"
-.It Ta Pa "linux" Ta "Linux"
-.It Ta Pa "svr4" Ta "AT&T System V Release 4"
-.It Ta Pa "esix" Ta "esix UNIX"
-.It Ta Pa "solaris" Ta "SunSoft Solaris"
-.It Ta Pa "irix" Ta "SGI IRIX"
-.It Ta Pa "sco	" Ta "SCO UNIX"
-.It Ta Pa "dell" Ta "Dell SVR4"
-.It Ta Pa "ncr  " Ta "NCR SVR4"
-.El
-.It Fl v
-Operate in verbose mode.
-.El
-.Pp
-The
-.Nm elf2olf
-and
-.Nm olf2elf
-utilities exit 0 on success or >0 if an error occurred.
-.Sh HISTORY
-The
-.Nm elf2olf
-and
-.Nm olf2elf
-utilities first appeared in
-.Ox 2.1 .
-.Sh AUTHORS
-Erik Theisen
-.Sh BUGS
-The
-.Em ELF
-version 1 object module format lacks any real method to determine the native
-operating system for any given binary thus mandating the existence of these
-tools.
-The converted binaries created by
-.Nm elf2olf
-will no longer execute on their native operating system, only on OLF
-enabled platforms, although
-.Nm olf2elf
-will undo the damage.
