A custom action is an action which will by added by a user to the
default behavior of IzPack. You should not change the standard
IzPack code self, else you write some java code which follows the
given rules. Custom actions are implemented as listener. Therefore
the name is (for uninstallation) <CustomName>UninstallerListener.
AntActionUninstallerListener is one implementation of an
UninstallerListener. I have done it to give a little bit complicated
example for users. Secondary it is full functional.
An other full functional example is RegistryUninstallerListener.

You can use the ant stuff for your problem. But may be to use
ant for some delete jobs in the uninstaller will be a little bit
over sized. On the other hand, if you are firm with ant it can
be the fastest implementation (only configuration files are neede).
Be aware, that a AntActionInstallerListener will be needed also
no action should be done at installation. It creates the
informations for the uninstaller and put it into the uninstaller.jar.

Have not to be (path and source can be elsewhere) but the simplest
is to use package
others are for java (and IzPack) experts.

An UninstallerListener is one way todo it. But it is not the only one.
An alternative is to write a batch or shell script and add it as
<executable> with stage="uninstall".
If you need the installation (or other system dependant) path in it,
you can use IzPack variables and use the <parseable> tag to revise.
May be this will be easier for you.
If needed, I have made an example last week to verify problems
Hans-Georg have had.
