I have an Ant script (version 1.5) to generate an executable JAR-file which
I use to deploy my Java application. The JAR-file has a manifest file
including a "Main-Class" tag to start the application as well as a "Class-
Path" tag to list the required libraries. However, if I inspect the
contents of the manifest file I see that Ant has inserted a CR-LF-SPACE
combination every 72 characters, thus corrupting the data. How can I create
a Class-Path entry in my JAR-manifest which is longer than 72 characters?
