<updatecheck> - Cleaning Up After Updates
This feature can update an installed package, to remove superfluous files after an installation.
Each pack can now specify an <updatecheck> tag that indicates which files are to be retained or deleted.
Includes and excludes can be defined as filesets, but no file name mappers can be used. If no include or exclude pattern is given all files are deleted in $INSTALL_Path on the target system, which were not part of the setup.
Be careful with this facility to not delete 3rd-party files coming from other installations, for instance plugins to a base application.
Example:
<updatecheck> Example
<updatecheck> <include name="lib/**" /> <exclude name="config/local/** /> </updatecheck>
$INSTALL_PATH is treated as the base path for include/exclude patterns with relative paths.
