A thesaurus at your fingertips
Synonymous is a simple Emacs plugin that allows you to select a word and replace it with a synonym or antonym. It
uses x-menu for offering choices, and the simple functions synonymous-synonyms and synonymous-antonyms for
displaying the selection menu.
It's paired with the synonymous server if you would like to run the server locally, otherwise it accesses an instance running on OpenShift.
