PDAConvert is a ebook corversor for the garnet devices.

I think that It's good to have alternatives.

In a future I want to see a "view text only" option in the pdf reader like you can see pocketxpdf, this is the only that i need for use evince as my default ebook reader, for now I need to convert the pdf to txt or pdb and then I read it with fbreader.
