Wikipedia: -ling, an English diminutive suffix
The easy way is to use pre-built railing utility:
Grab a binary named railing-<version> from releases.
Rename the binary to railing and move it to your Erlang project directory.
Create the image and the domain configuration file:
./railing image
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.
