# A simple python build script to build the singles/stages/stagers and
|
||||
# some usefull information such as offsets and a hex dump. The binary output
|
||||
# will be placed in the bin directory. A hex string and usefull comments will
|
||||
# be printed to screen.
|
||||
#
|
||||
# Example:
|
||||
# >python build.py stager_reverse_tcp_nx
|
||||
#
|
||||
# Example, to build everything:
|
||||
# >python build.py all > build_output.txt
