libmatheval1 1.1.7-2 (armel binary) in ubuntu oneiric

 GNU libmatheval is library comprising several procedures that makes
 possible to create in-memory tree representation of mathematical
 functions over single or multiple variables and later use this
 representation to evaluate function for specified variable values, to
 create corresponding tree for function derivative over specified
 variable or to print textual representation of in-memory tree to
 specified string. The library supports arbitrary variable names in
 expressions, decimal constants, basic unary and binary operators and
 elementary mathematical functions.
 This package contains the runtime shared libraries.
