Overwrites the contents of the current synonym manifest in the application. The contents of the manifest will consist of all key-value synonym pairs, represented as a JSON array, that are known in the system. A key value pair is denoted as X=>Y where X is a word that will be a synonym of word Y. Please observe that while the rule confirms that word X will be a synonym of word Y, that does NOT imply that word Y will also be a synonym of word X. If you desire to add on this inverse relationship, Y=>X must also be specified in the manifest as a separate item.
