     elf2olf, olf2elf - convert between ELF and OLF object module
format

SYNOPSIS    [Toc]    [Back]

     elf2olf [-v] [-o opsys] module [...]
     olf2elf [-v] file [...]

DESCRIPTION    [Toc]    [Back]

     The elf2olf utility reads the specified ELF version 1 module
operands and
     converts them to the default operating system's  OLF  object
module format.

     The  olf2elf  utility  reverses  the  process.   The  module
operands are processed
 in command line order.

     The options are as follows:

     -v      Operate in verbose mode.

     -o opsys
             Specifies the operating system OLF tag opsys as follows:

BUGS    [Toc]    [Back]

     The 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
elf2olf will no
     longer execute on their native operating system, only on OLF
enabled
     platforms, although olf2elf will undo the damage.
