its execute() method, because the perform() method (implemented in Task itself) does the
appropriate logging before and after invoking execute().
++ Here is an example of using beanshell to create an ant + task. This task will add filesets and paths to a referenced + path. If the path does not exist, it will be created. +

++ An example of using this task to create a path + from a list of directories (using antcontrib's + + <for> task) follows: +
+
+<path id="main.path">
+ <fileset dir="build/classes"/>
+</path>
+<ac:for param="ref" list="commons,fw,lps"
+ xmlns:ac="antlib:net.sf.antcontrib">

+ </addtopath>
+ </sequential>
