-Babel is a conversion program which is able to convert among dozens of
-molecular file formats. 
-Babel is developed by Dolata Group, Department of Chemistry,
-Arizona University and Ohio State University.
+Babel is a program designed to interconvert a number of file formats
+currently used in molecular modeling.  Babel is capable of assigning
