Gretools released -- GNOME vocabulary builder

I have released gretools, a vocabulary building tool for GNOME. It is a fun and efficient way to learn new words. Gretools consists of a synonym quiz and a word guessing game and also allows you to look up words. It automatically remembers the words you got wrong and helps you revise those words. You can set a filter to restrict the space of words to practice on. Gretools is extremely useful for preparing for word tests.
