The configuration is very similar to the navigation asset, and indeed it is based on that (in fact, it probably has some code leftover from nav that could be gotten rid of).
This is a better, more generalized replacement for the RecentPosts macro I posted recently as well.
The zip file contains the asset module, the i18n file, the help file, two sample templates, and a template install script.
To install:
cd $webguiRoot/lib/WebGUI
unzip $path_to_AssetReport.zip/AssetReport.zip
. /data/wre/sbin/setenvironment (if not running in the WRE, skip that)
(sudo) perl install_templates.pl
Add "WebGUI::Asset::Wobject::AssetReport" to your list of assets in your configuration file
Restart WebGUI
Update: This version now works with order by fields that aren't in the asset table (for example, you can order by a userDefinedX field in collab system posts).
