I know there was already some talking about it. But not very clearly
So I insist:
an OCR to use wherever you are would be useful for a lot of people
I know, GOCR is not the very best, but it seems to respond to the requirements of portable apps:
GOCR is an OCR (Optical Character Recognition) program, developed under the GNU Public License. It converts scanned images of text back to text files. Joerg Schulenburg started the program, and now leads a team of developers.
GOCR can be used with different front-ends, which makes it very easy to port to different OSes and architectures. It can open many different image formats, and its quality have been improving in a daily basis.
so why not use this?
