SMILE is a slideshow building program by Stephane Gibault, author of manDVD, and is the successor to manslide.
Currently it’s not possible to use both manDVD and SMILE since they make use of different versions of sox tools. The successor of manDVD (called 2manDVD on which the Stephane is currently working on) will be compatible with SMILE.
SMILE is provided on the official website in source code only, you may follow this tutorial in order to know how to compile it, or else may use Andrea Gasparini PPA. Let’s explain the latter first.
