/**
*
* Parsing deployer for {@code pooling.yml}.
*
* <p>
* This deployer looks for metadata files named exactly {@code pooling.yml},
* which is expected to be a YAML file describing the configuration of various
* Ruby runtime interpreter pools.
* </p>
*
* <p>
* The top-level of the YAML file should be a hash, with the pool identifier as
* the key. The value of each map may be the strings {@code global} or
* {@code shared}, or another hash specifying {@code min} and {@code max} values
* for the pool size.
* </p>
*
* <pre>
* pool_one: global
* pool_two: shared
* pool_three:
* min: 5
* max: 25
* </pre>
