 ### Single-File Design
-The entire application logic resides in `app/src/main/java/jrunner/jrunner.java`. This is a monolithic command-line tool with no abstraction layers or separate modules.

 The tool includes explicit handling for different SQL data types in a switch statement (lines 229-312). Supported types include VARCHAR, TEXT, CHAR, CLOB, DATE, TIME, TIMESTAMP, and BIGINT. String types get quote escaping and optional trimming.

+### using the deploy script (recommended)
+
+First, create the deployment directory:
 ```
-sudo unzip app/build/distributions/app.zip -d /opt/
-sudo ln -sf /opt/app/bin/app /usr/local/bin/jrunner
+sudo mkdir -p /opt/jrunner
 ```
 
-Now you can run from anywhere:
+Then deploy:
+```
+# Deploy to /opt/jrunner (default, creates system-wide symlink)
+./deploy.sh
+
+# Deploy to custom location (for testing, no symlink)
+sudo mkdir -p /opt/jrunner-test
+./deploy.sh /opt/jrunner-test
+```
+
+The script builds, extracts to a temporary location, and only updates the target directory after the build succeeds. This ensures your existing deployment stays intact if the build fails. When deploying to `/opt/jrunner`, it creates a symlink at `/usr/local/bin/jrunner`.
+
+### manual deployment
+```
+./gradlew build
+sudo unzip jrunner/build/distributions/jrunner.zip -d /opt/
+sudo ln -sf /opt/jrunner/bin/jrunner /usr/local/bin/jrunner
+```
+
+## usage

+After deployment to default location:
 ```
 jrunner -scu jdbc:postgresql://... -scn user -scp pass ...
