optical structure recognition (shared library)

 OSRA is a utility designed to convert graphical representations of
 chemical structures, as they appear in journal articles, patent documents,
 textbooks, trade magazines etc., into SMILES (Simplified Molecular
 Input Line Entry Specification) - a computer recognizable molecular structure
 format. OSRA can read a document in any of the over 90 graphical formats
 parseable by ImageMagick - including GIF, JPEG, PNG, TIFF, PDF, PS etc., and
 generate the SMILES representation of the molecular structure images
 encountered within that document.
