Wikipedia: -ling, an English diminutive suffix

The easy way is to use pre-built railing utility:

1. Grab a binary named railing-<version> from releases.

2. Rename the binary to railing and move it to your Erlang project directory.

3. Create the image and the domain configuration file:

    ./railing image
   

4. Boot the Xen domain and get the familiar Erlang shell:

    xl create -c domain_config
   

See INSTALL.md.

Run railing without options to get help.

To generate the image and the domain configuration file use the image subcommand:

./railing image

This instructs railing to scan all subdirectories for *.beam files. All files found are embedded into the Xen image and become accessible during runtime. Certain subdirectories can be excluded from the search using -x option.
