In mu-template case, that I'm maintaining, you'll have to register at least 4 plugins in your plugin manager -- yeah, I know, 4 seems a lot, but I don't like duplicating my code, and I'm dreaming of a day when people will use plugin managers that handle dependencies...
The main, required, plugins:
The optional one to have a multi-cursors like feature
Another optional one used in a few default snippets
And I have even more snippets in lh-cpp for C++ and C
Then you also need to be aware of the old, and non-usual, approach taken in mu-template regarding placeholders as it could be really confusing.
