## How to run? ##

1. Download Frege REPL archive from [releases](https://github.com/Frege/frege-repl/releases).

1. Extract the archive

1. Run the following command: (JDK 8 or above required. Note that JDK is required, not just JRE as Frege is compiled to Java which is then compiled to byte code using the Java compiler available in the JDK)

          $ frege-repl-/bin/frege-repl

     

     or if you want to customize JVM parameters:

     `java -cp "frege-repl-/lib/*" frege.repl.FregeRepl`

As of late, the REPL is included in [frege releases](https://github.com/Frege/frege/releases).
