If *installable* evaluates to a derivation, it will try to execute the
program `<out>/bin/<name>`, where *out* is the primary output store
path of the derivation and *name* is the name part of the value of the
`name` attribute of the derivation (e.g. if `name` is set to
`hello-1.10`, it will run `$out/bin/hello`).
path of the derivation and *name* is the `meta.mainProgram` attribute
of the derivation if it exists, and otherwise the name part of the
value of the `name` attribute of the derivation (e.g. if `name` is set
to `hello-1.10`, it will run `$out/bin/hello`).
