The execute task works similar to the call task except that is executes a bunch of tasks instead of a target.

The tasks to execute are defined as inner elements of the execute task.

Name	Description	Required
if	Executes the target task if a property named as the value exists.	yes (if no other condition was defined).
unless	Executes the target task if no property named as the value exists.	yes (if no other condition was defined).
while	Executes the target task again and again while a property named as the value exists. The loop will be aborted if the property no more exists. I'm not really sure but probably this condition may be senseless because Ant properties are immutable. Be careful using this condition. You may configure endless loops !	yes (if no other condition was defined).
