Re: [Savannah-hackers] copyright, png and pngcrush

[Yves Mettier]

Coucou!

It should have be done a long time ago (more than 1 year!!!): done!
The documentation about how to set the copyright and the licence
inside the cards (png images) is online.

Ca faisait longtemps que ca aurait du etre fait (plus d'un an!!!):
c'est fait! J'ai mis en ligne la maniere dont le copyright et la
licence sont mises a l'interieur des cartes (images png).
