gsculpt is dead

This great 3d modeling application is dead, I send an email to the developer to know about the future and this is the answer it gives me.

Dear Rafael,

Unfortunately, I don’t seem to have much time for working on gSculpt any more, and I have moved on to other projects.
Thanks for your interest though.

the point is the blender developer cant see and implement some of the tools behavior this aplication have like the knife tool is excelent. and the bevel and sweep-extrude.
