if clause

[Tibor Strausz <Ti...@tridion.com>]

i wonder how ant live would be if there would be an <if> task wich can hold
other task as its sub tasks.
the sub task gets executed when the if has a property which is true or set.

is ther shuch a task??
if not, why????

tibi


example i could do this
