lookup cache dump?

[magikRUKKOLA]

Is there any docs regarding this option:

grep -rn -Fa --colour 'lookup_cache_dynamic' --include='*.cpp'
examples/lookup/lookup-stats.cpp:57:        if (!params.lookup_cache_dynamic.empty()) {
examples/lookup/lookup-stats.cpp:59:                ngram_cache_dynamic = llama_ngram_cache_load(params.lookup_cache_dynamic);
examples/lookup/lookup.cpp:67:        if (!params.lookup_cache_dynamic.empty()) {
examples/lookup/lookup.cpp:69:                ngram_cache_dynamic = llama_ngram_cache_load(params.lookup_cache_dynamic);
examples/lookup/lookup.cpp:226:    llama_ngram_cache_save(ngram_cache_dynamic, params.lookup_cache_dynamic);
common/common.cpp:1143:        params.lookup_cache_dynamic = argv[i];

There should be a client written to save and load the cache?
