Setting a property based on the OS
Is it possible to set a property based on the OS?
For eg consider the following folder setup
redist
|- win32
|- mac
|- linux
I would like to set a property ${redistdir} based on the OS and then use it
to copy redistributable files from the relevant folder.
If there is a better way to accomplish this. Please let me know.

<condition> is just a task like <available> (a more general form of it
actually).
You can find the docs in the 1.4beta distribution as well as here:
<http://cvs.apache.org/viewcvs/~checkout~/jakarta-ant/docs/manual/CoreTasks/condition.html?rev=1.1&content-type=text/html>.

I've not seen the docs for the <condition> task, so was wondering how ot
integrate its use with a <target>
That's all.

How would this then be used in a target?

Actually you can do something more automatic than having to manually set a
property. You can define a property like this:
<property name="is${os.name}" value="whatever"/>
And replace your 'if' statement below with things like:
if="isWindows 2000"

Another possible way to do this in version 1.3 would
be to set up a different property for each OS, and
then test for the existence of that property.
Your command line would read...
... -Dlinux=true ...
or
... -Dwindows=true ...
The value after the property ("true") would only exist
for documentation and wouldn't be used.
In Ant you would then code...
<target name="processLinux" if="linux">
...
</target>
<target name="processWindows" if="windows">
...
</target>
<target name="processOS">
<antcall target="processLinux"/>
<antcall target="processWindows"/>
</target>
