+     *      In brief, a descriptor is a string representing the type of a field or method. Signatures are similar, but more
+     *      complex. Signatures are used to encode declarations written in the Java programming language that use types
+     *      outside the type system of the Java Virtual Machine. They are used to describe the type of any class, interface,
+     *      constructor, method or field whose declaration uses type variables or parameterized types.
+     *
+     *      To parse a descriptor, call typeSignatureToString. To parse a signature, call signatureToString.
+     *
+     *      Note that if the signature string is a single, non-generic item, the call to signatureToString reduces to a call
+     *      to typeSignatureToString. Also note, that if you only wish to parse the first item in a longer signature string,

-     *
-     * There is some nomenclature confusion through much of the BCEL code base with

-     *
-     * @see 
-     * Descriptors in The Java Virtual Machine Specification
-     *
-     * @see 
-     * Signatures in The Java Virtual Machine Specification
-     *
-     * In brief, a descriptor is a string representing the type of a field or method.
-     * Signatures are similar, but more complex.  Signatures are used to encode declarations
-     * written in the Java programming language that use types outside the type system of the
-     * Java Virtual Machine.  They are used to describe the type of any class, interface,
-     * constructor, method or field whose declaration uses type variables or parameterized types.
-     *
-     * To parse a descriptor, call typeSignatureToString.
-     * To parse a signature, call signatureToString.
-     *
-     * Note that if the signature string is a single, non-generic item, the call to
-     * signatureToString reduces to a call to typeSignatureToString.
-     * Also note, that if you only wish to parse the first item in a longer signature
-     * string, you should call typeSignatureToString directly.
