Don't laugh... I'm a newbye (and french) : only one week of practice on Linux. I need one of these three actions for many files types of my own (but always text files), and I always have to open a dialog box to choose an application although it's very often one of those.
The installation is as basic as possible : uncompress, chose one (or several within the 6) file(s) regarding to your language, and copy it (them) in your service menus folder. That's all.
No dependancies. No mysteries.
I guess it could help at least some beginners like me.
Locales are french and english. Easily adaptable by everyone.
Friendship for all !
