To do the deb shouldn't be that hard, add depend for pypackager. Have a UI to enter vars. package name,description, author,email,bugtracker. You will need to move the theme images into a folder to build the package. You need the source files in a folder called something like src that has the right folder structure like /usr/share/theme/'themename'. then have program out put the updated build_myapp.py then execute the python file it will output the deb or source fies depending on what you have it set to in script. If you need any help with it let me know. I do this funny thing with my themes I build them first time using autobuilder then after I get theme right to add icons I build them using pypackager.
