In `tools/build.py`: - For the sake of readability, group CLI arguments as general build options, options to control the building of components, and component-specific options. - To prevent duplications, remove the defaults from those CLI arguments that correspond to CMake options and have defaults in any of the CMakeLists. Should any of the defaults change, they will have to be changed at a single place only. (Those options that are not set on the command line of `tools/build.py` are not passed as options to `cmake` either.) - Convert `--unittests` and `--doctests` to ON/OFF options like the rest of the component switches. - Touch on some of the help messages of the CLI arguments. Other changes: - The change in `--unittests` and `--doctests` is a slightly CLI- breaking change of `tools/build.py`. Thus, follow up on this in `tools/run-tests.py`. - Move `ENABLE_ALL_IN_ONE` into `jerry-core` as it is not a general option but specific to that component. - Remove the forcing of `ENABLE_ALL_IN_ONE` for some compilers/ platforms as it is still an option, not a hard requirement.

JerryScript: JavaScript engine for the Internet of Things
JerryScript is a lightweight JavaScript engine for resource-constrained devices such as microcontrollers. It can run on devices with less than 64 KB of RAM and less than 200 KB of flash memory.
Key characteristics of JerryScript:
- Full ECMAScript 5.1 standard compliance
- 160K binary size when compiled for ARM Thumb-2
- Heavily optimized for low memory consumption
- Written in C99 for maximum portability
- Snapshot support for precompiling JavaScript source code to byte code
- Mature C API, easy to embed in applications
Additional information can be found on our project page and Wiki.
Memory usage and Binary footprint are measured at here with real target daily.
The following table shows the latest results on the devices:
| STM32F4-Discovery |  |
|---|---|
| Raspberry Pi 2 |  |
| Artik053 |  |
