Fix translated description

Dette er et OCR-program (»Optical Character Recognition«, optisk tegngenkendelse) for flere platforme.

Programmet kan læse billedfilerne pnm, pbm, pgm, ppm, nogle pcx og tga.

På nuværende tidspunkt burde programmet være i stand til god håndtering af skanninger, der har deres tekst i én kolonne uden tabeller. Skriftstørrelser på 20 til 60 billedpunkter understøttes.

Hvis du ønsker at skrive din egen OCR, så tilbydes libgocr i en separat pakke. Dokumentation og grafisk omslag tilbydes også i separate pakker.
