Tepache is a code sketcher for python that uses pygtk and glade.
There is libglade, there is pygtk-libglade. Then, tepache does not have to create any code for creating the graphical interfaces. It creates pure python modules with classes that are clean abstractions for the toplevel widgets of the glade files. That is why we say tepache is not a code generator, it is a code sketcher.
Typical code generators overwrite your own code every time they are executed. Tepache won't lost your code because it uses a very simple system of using context comments for protecting your code. It could look a little verbose but works very well.
