You can create closed-source programs (even commercial ones) with this compiler
(a mention to this tool will be welcome, though). But you are not allowed to
release the compiler itself as a closed source program.

If you modify *this* project (the compiler .py or anything licensed as AGPLv3)

you made and submit your contribution to the community under the same license.

DOCUMENTATION
-------------

This is a very little help file.

 - For DOCUMENTATION in English go to the [ZX BASIC docs](https://zxbasic.readthedocs.io/en/latest/).

 - For help, support, updates meet the community at the [forum](https://www.boriel.com/forum).


INSTALLATION
------------

Go to the [ZXBasic download page](https://zxbasic.readthedocs.io/en/latest/archive/)
and get the version most suitable for you.

There are, basically, two flavors (both with identical capabilities):

 - For Windows you can download de win32 executable (Windows .exe zip package) version.
To install just uncompress it in a directory of your choice.
The main executable is `zxbc.exe` (more on this later). With this toolchain
also comes `zxbasm.exe` (the assembler) and `zxbpp.exe` (the preprocessor), but these
are not needed when programming in BASIC.

 - For Linux and Mac OSX there is a python version, so you will need a python
interpreter (available on many platforms, and usually already installed in Linux and Mac OSX).
Just uncompress it in a directory of your choice and installation is done. :-)
The main executables are `zxbc.py` (the compiler), `zxbasm.py` (the assembler) and `zxbpp.py` (the preprocessor).
You can use this version in Windows, but will need to install a python interpreter first.

QUICK START
-----------

For a quick start, just open a terminal in your PC in the same directory you uncompressed ZX Basic
and type `zxbc` (on Windows) or `zxbc.py` (OSX, Linux). You should see a zxbasic message like this:

```
usage: zxbc [-h] [-d] [-O OPTIMIZE] [-o OUTPUT_FILE] [-T] [-t] [-B] [-a] [-A]
           [-S ORG] [-e STDERR] [--array-base ARRAY_BASE]
           [--string-base STRING_BASE] [-Z] [-H HEAP_SIZE]
           [--heap-adddress HEAP_ADDRESS] [--debug-memory]
           [--debug-array] [--strict-bool] [--enable-break] [-E] [--explicit]
           [-D DEFINES] [-M MEMORY_MAP] [-i] [-I INCLUDE_PATH] [--strict]
           [--version]
           PROGRAM
zxbc: error: the following arguments are required: PROGRAM
```

Create a text file with the following content:

~~~~
10 CLS
20 PRINT "HELLO WORLD!"
~~~~

Save it as `hello.bas` and finally compile it with:
~~~~
zxbc -taB hello.bas
~~~~

If everything went well, a file named `hello.tap` should be created.
Open it with your favourite emulator (i.e. fuse) and see the result.

Congratulations! You're now ready to create compiled BASIC programs for
your machine. Check and compile the examples included in the examples/ folder
or go to the [documentation page](https://zxbasic.readthedocs.io/en/latest/) for further info.
