I didn't think to declare the toolbox as package. Your version works fine. Thanks. I pushed it to the Versionner repo. :) So, now Versionner is loadable as any other lib. @Marcus: Yes, if possible, it should be nice to update the toolbox version in the image.

It is nice. ;) Actually Snappy itself is optimized for 64-bit platform. So you may need a recompilation if you try it in 64 bit VM. Best regards, -- [:masashi | ^umezawa]

[Pharo-project] SS lost project description edits done in december 2012

by GÃ¶ran Krampe

Hi! I moved a lot of my projects to StHub back in december, and then I edited the Project descriptions on SS to show that. But these changes have been lost I now realize? Just put it back on Phriak: http://www.squeaksource.com/Phriak.html Any idea on when/how that happened? regards, GÃ¶ran
