NAME
segedit - extract and replace sections from object files
SYNOPSIS
segedit [ option ] name ... input_file [-extract segname sectname
filename] ... [[-replace segname sectname filename] ... -output out-
put_file]
DESCRIPTION
Segedit extracts and or replaces the named sections from the input_file
and creates an output_file (if replacing a section). The segment and
section names are the same as specified to ld(1) with the -segcreate
option. The segment and section names of an object file can be exam-
ined with the -l option to otool(1). Only sections in segments that
have no relocation to or for them can be replaced (marked with the
SG_NORELOC segment flag) but all sections can be extracted.
The options to segedit(1):
-extract segname sectname filename
Extracts the section specified by the segment name section name
pair and places the contents in the specified filename.
-replace segname sectname filename
Will replace the section specified by the segment name section
name pair and places and take the new contents for the section
from the specified filename. The -output filename option must
also be specified. The resulting size of the section will be
rounded to a multiple of 4 bytes and padded with zero bytes if
necessary.
-output output_file
Specifies the output file to create when replacing sections.

LIMITATIONS
Only mach-O format files that are laid out in a contiguous address
space and with their contents ordered in the order of increasing
address can have their segments replaced by this program. This layout
is what the link editor produces by default.
