/**
* ({@code @wurblet}) Generate code for setting up a PdoCache for an entity.
*
* usage:
* @wurblet <tag> PdoCache
* [--secure] [--preload] [--mutable] [--udk]
* [--strategy=LRU|LFU|FORGET] [--maxsize=<n>] [--keepquota=<p>] [--configure=<method>]
* [index1] [index2] ...
*
* arguments:
*
* - --secure: if cache must check read permission for each access (default is no check).
* - --preload: the first access will load all entities at once.
* - --mutable: generates a non-shared cache, i.e. mutable PDOs (by default a shared readonly cache is generated).
* - --udk: add index for the unique domain key.
* - --strategy=LRU|LFU|FORGET: the caching strategy (default is FORGET).
* - --maxsize=<n>: the cache size (if not preloaded).
* - --keepquota=<p>: percentage of entries to keep when applying caching strategy. Default is 50.
* - --configure=<method>: an optional method to further configure the cache.
* - --index<n>: additional unique indexes. By default, only the ID-index will be created.
*
* For more options, see {@link DbModelWurblet}.
