# get.sh script

get.sh script does the following:

- Makes sure you have a supported version of Go toolchain, if this is not the
  case - it downloads one.
- Downloads and compiles maddy executables.
- Installs maddy executables to /usr/local/bin.
- Installs the dist/ directory contents
- Installs the man/ directory contents
- Install the default configuration.
- Creates maddy user and group.

It is Linux-specific, users of other systems will have to use Manual
installation.
