This tool downloads eggnog data using download_eggnog_data.py and populates the data tables: eggnog_mapper_db and eggnog_mapper_hmm_dbs. The data is located at: http://eggnogdb.embl.de/download/emapperdb-4.5.1/ The optional eggNOG HMM databases: http://eggnogdb.embl.de/download/emapperdb-4.5.1/hmmdb_levels/ can vary from 1G to 80G in size.

The data will be downloaded to the specified directory. This allows adding hmmdb_levels to an existing download. You should not mix eggnog data versions in the same directory.
