This is a fork of the excellent Java Expression Parser (JEP) based on JEP 2.23.

The main changes are:

• Ability to override basic arithmetic operators (e.g., +, -, *, /). In order to do so, just use

  parser.addFunction("\"+\"", new CustomAdd());

• Conformance to Java 7

In order to build it, just launch a terminal and issue ./compile.sh. There is also a possibly outdated Ant script, but I didn't test it.
