Inkscape is very powerful, but too complex for me, to make occasional drawings like here.
Do you know some simpler alternatives (open source, for a Linux Debian desktop, to make vector not bitmap drawings), and compatible with a wacom pen. In an ideal world, something scriptable with Guile ? I googled and found this.
It should be open source, because I might patch it (e.g. to add Guile scriptability)
