Geany Dev Team:
I will create a GTK3-based application that creates Debian (*.deb) files. Once it is done, I will upload the src to my website (DCJTech.info), and then, I will share the link to the application. Thus, we can more easily generate *.deb files for Geany.
By the way, sometime this week or next week, I will add the Squirrel filetype to the wiki.
