Alas !
The new version of Fiasco Mustache is out ! You can test it now on the Demo Page !
The UI has been revised, and the PDF generation is now fully integrated. No need to use the Mustache generator to produce Scribus file to produce PDF. Just click on "Generate PDF !"
Again, if you need improvements, find bugs or need help, go through an Issue and report that !
