## Get CAF

### FreeBSD Ports

We maintain a port for CAF, which you can install as follows:

```sh
pkg install caf
```

Alternatively, you can go to `/usr/ports/devel/caf` and tweak a few
configuration options before installing the port:

```sh
make config
make install clean
```

### Homebrew

You can install the latest stable release with:

```sh
brew install caf
```

Alternatively, you can use the current development version by using:

```sh
brew install caf --HEAD
```

### Conan

A [Conan](https://conan.io/) recipe for CAF along with pre-built libraries
for most platforms are available at [bincrafters/caf](https://bintray.com/bincrafters/public-conan/caf%3Abincrafters).

### VCPKG

You can build and install CAF using [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager with a single command:

```sh
vcpkg install caf
```

The caf port in vcpkg is kept up to date by Microsoft team members and community contributors.

## Get the Sources

* git clone https://github.com/actor-framework/actor-framework.git
* cd actor-framework

## Build CAF from Source

The easiest way to build CAF is to use the `configure` script. Other available
options are using [CMake](http://www.cmake.org/) directly or
[SNocs](https://github.com/airutech/snocs).

### Using the `configure` Script

The script is a convenient frontend for `CMake`. See `configure -h`
for a list of available options or read the
[online documentation](https://github.com/actor-framework/actor-framework/wiki/Configure-Options).

```sh
./configure
make
make test
make install [as root, optional]
```

### Using CMake

All available CMake variables are available
[online](https://github.com/actor-framework/actor-framework/wiki/CMake-Options).
CAF also can be included as CMake submodule or added as dependency to other
CMake-based projects using the file `cmake/FindCAF.cmake`.

### Using SNocs

A SNocs workspace is provided by GitHub user
[osblinnikov](https://github.com/osblinnikov) and documented
[online](https://github.com/actor-framework/actor-framework/wiki/Using-SNocs).

## Dependencies
