Follow instructions in COMPILE.TXT for how to compile and run test code.

Note: if you find some strange bugs, it is recommended to firstly clean
the code and try to recompile/reinstall again. This can be done with:

	$ ./make.sh
	$ sudo ./make.sh install

Then test Capstone with cstool, for example:

	$ cstool x32 "90 91"

At the same time, for Java/Ocaml/Python bindings, be sure to always use
the bindings coming with the core to avoid potential incompatibility issue
with older versions.
See bindings/<language>/README for detail instructions on how to compile &
install the bindings.


Coding style
------------
- C code follows Linux kernel coding style, using tabs for indentation.
- Python code uses 4 spaces for indentation.


Adding an architecture
----------------------

Obviously, you first need to write all the logic and put it in a new directory arch/newarch
Then, you have to modify other files.
(You can look for one architecture such as EVM in these files to get what you need to do)

Integrate:
- cs.c
- cstool/cstool.c
- cstool/cstool_newarch.c: print the architecture specific details
- include/capstone/capstone.h
- include/capstone/newarch.h: create this file to export all specifics about the new architecture

Compile:
- CMakeLists.txt
- Makefile
- config.mk

Tests:
- tests/Makefile
- tests/test_basic.c
- tests/test_detail.c
- tests/test_iter.c
- tests/test_newarch.c
- suite/fuzz/fuzz_disasm.c: add the architecture and its modes to the list of fuzzed platforms

Bindings:
- bindings/Makefile
- bindings/const_generator.py: add the header file and the architecture
- bindings/python/Makefile
- bindings/python/capstone/__init__.py
- bindings/python/capstone/newarch.py: define the python structures
- bindings/python/capstone/newarch_const.py: generate this file
- bindings/python/test_newarch.py: create a basic decoding test
- bindings/python/test_all.py

Docs:
- README.md
- HACK.txt
- CREDITS.txt: add your name
