-Spring Integration Zip Sample
-===================
-
-This sample illustrates the usage of the Spring Integration Zip Extension. It uses the following components:
-
-* zip-transformer
-* unzip-transformer
-
-You can run the application by either
-
-* running the "Main" class from within STS (Right-click on Main class --> Run As --> Java Application)
-* or from the command line:
- - mvn package
- - mvn exec:java
-
-You should see a screen as the following:
-
-```
