TeXamator is written in Python/Qt4. It is aimed at helping you making your exercise sheets. Basically, it browses a specified directory, looks for .tex files containing exercices and builds a tree with all your exercises. You can click on an element of the tree to have a preview of the exercise sheet and then add exercises to a list if you wish to. Then you can save your work to a .tex file or you can generate a .dvi (or a pdf or a ps) file. Have a look at the screenshots (not up to date but they still give an overview of the programm) !
