The template notation spike is documented in a issuezila task (#3802).
Today I contributed my eclipse project files to ArgoUML list, in a reply to a discussion about shared eclipse projects.
As an ArgoUML contributor I'm going to blog my activities here, so that they may draw interest by other developers or help other developers when doing tasks similar to what I've done. AND(!) the grand vision that makes an Argonaut what he is, TO THRIVE IN THE BIG DANGEROUS WORLD, TAKING THE Argo TO A GOOD SHORE ;-))
