NAME

       lfanew - manipulate fat binary programs wrapped in MZ files

SYNOPSIS

       lfanew [-k] -o <out-stub-file> <in-stub-file>
       lfanew -S [-k] [-p] -o <out-fat-file> <in-payload-file> <in-stub-file>
       lfanew -U [-k] -o <out-payload-file> <in-fat-file>

DESCRIPTION

       By  default,  lfanew  adds a .e_lfanew header field to an old-style MZ executable, so that
       the program can be used as an MS-DOS loader stub for a NE/PE executable.

       With -S ("stubify"), lfanew creates a "fat" binary by combining an MZ stub  with  a  NE/PE
       payload.

       With  -U  ("unstubify"), lfanew extracts a NE/PE payload from a "fat" binary, removing any
       MZ stub.

OPTIONS

       -k      Keeps the output if an error is encountered, instead of deleting it.

       -p      Derives the stub size from .e_cp and .e_cblp, rather than from .e_lfanew.

NOTES

       lfanew can add a stub to a Portable Executable payload if there is enough RVA space before
       the  PE sections to accommodate the stub and PE headers.  PE executables generally need to
       be unstubified before a different stub can be attached.
