"Claire is a high-level functional and object-oriented language with "
"advanced rule processing capabilities. It is intended to allow the "
"programmer to express complex algorithms with fewer lines and in an "
"elegant and readable manner. "
""
"To provide a high degree of expressivity, Claire uses: "
"@itemize"
"@item"
" A very rich type system including type intervals and second-order "
" types (with dual static/dynamic typing),"
"@item"
" Parametric classes and methods, "
"@item"
" An object-oriented logic with set extensions, "
"@item"
" Dynamic versioning that supports easy exploration of search spaces. "
"@end itemize"
"To achieve its goal of readability, Claire uses "
"@itemize"
"@item"
" set-based programming with an intuitive syntax, "
"@item"
" simple-minded object-oriented programming, "
"@item"
" truly polymorphic and parametric functional programming, "
"@item"
" a powerful-yet-readable extension of DATALOG to express logical conditions,"
"@item"
" an entity-relation approach with explicit relations, inverses, "
" unknown values and relational"
"@item"
" operations. "
"@end itemize"
