        This class does not need to be instantiated.
    • Method Detail

      • main

        public static void main​(java.lang.String[] args)
        Program that computes the dependencies between the Batik jars.

        Run this from the main Batik distribution directory, after building the jars. For every jar file in the batik-xxx/ build directory, it will determine which other jar files it directly depends on. The output is lines of the form:

          number,from,to

        where mean that the from jar has number class files that depend on class files in the to jar.
