+**What this tool does**
+
+OSRA_ (Optical Structure Recognition Application) is a utility designed to convert graphical representations of chemical structures into SMILES or SDF. It generates the SMILES or SDF representation of any molecular structure image within a document which is parseable by GraphicMagick.
