# This script generates a JSON .nmf file, which provides the mapping to indicate
|
|
# which .nexe file to load and execute for a particular architecture.
|
|
# The script must have -nmf <filename> as an option, which designates the name
|
|
# of the .nmf file to be generated.
|
|
# One or more nexes must be specified on the command line. Each
|
|
# nexe file is preceded by an argument that specifies the architecture
|
|
# that the nexe is associated with: --x86-64, --x86-32, --arm.
|
|
#
|
|
# For example:
|
|
# generate_nmf.py --nmf test.nmf --x86-64 hello_world_x86-64.nexe \
|
|
# --x86-32 hello32.nexe
|
|
# will create test.nmf that contains 2 entries, while
|
|
#
|
|
# generate_nmf.py --nmf hello.nmf --arm arm.nexe
|
|
#
|
|
# will create hello.nmf with a single entry.
