Since Jeql is a JavaTM application,
it runs on any platform which has Java 1.4 or higher installed.
The following instructions are written for a Microsoft WindowsTM target system.
The installation on other operating systems is similar.
To install Jeql on a Microsoft Windows system, following the following steps
Ensure that Java 1.4 or higher is installed on the target system.
Create a home directory for the Jeql application. For example, C:\apps\jeql.
This directory will be referred to as [JEQL_HOME] in the following steps.
Unzip the Jeql installation archive into the [JEQL_HOME] directory
It is recommended that [JEQL_HOME]\bin be added to the system path
(using whatever procedure is appropriate to the specifice version of Windows)
If this is not done, the jeql command will need to be prefixed with [JEQL_HOME]
whenever it is used.
Testing the Installation
To confirm that Jeql has been installed correctly, do the following:
Open a Windows Command Prompt window.
One way to do this is to run the cmd.exe application from the Start/Run... dialog
Run the following command:
(this assumes that the Jeql installation has been added to the system path)
jeql -help
If Jeql is installed correctly, you will see output similar to the following:
Jeql 0.8 ---- (c) 2007-2009 Martin Davis ---- Java 1.6.0_07
jeql [-help] [-quiet] [-man] [<script filename> <script arg> ...]
