Sander Vesik aa4508042d INTEGRATION: CWS scriptingf5 (1.8.2); FILE MERGED 
2004/03/31 08:42:29 dfoster 1.8.2.2: #i27220#
Basic provider not showing the user libs.
2004/03/05 10:33:43 npower 1.8.2.1: #i22570# Changes to support new URL parsing service. A side affect of using the new service is that the format of the URI has changed a little. The URI is now nt hierarchical. Changes to the files below involve removing methods to parse data from the URI instread new service UriReferenceFactory, adding the new types to build project xml  files.
