CCL: info about .MOL files needed



Hi,
 
  I´m new to CCL, sorry if this question has been previously answered, but CCL search capabilities seems to be disabled. I would like to know if anyone can help me: I need the specification of .MOL files to build a parser to extract molecule information. Is there a free parser available?
  Any usefull information will be apreciated.
 
  Thank you in advance. Roman Garcia.
