# Working With Build and Analysis Tools

The Admin Tool includes utilities to perform the following:

- Building Expere content repositories in REQ and legacy ERL formats
- Generating Requirements and Content .xml*or databases
- Building and loading REQ and ERL formats to Expere Runtime
- Load to Expere Runtime

The Admin Tool also includes an Impact Analysis Report. When you generate the report it compares the new content to the existing content and will show the effects of updating that content. The Impact Analysis report summarizes the number of new and updated documents, and it identifies the automatic and any conflicted merge points. Conflicted merge points are highlighted, so you can find and click each one to see a description of the conflict (error).

In a.xml*ion to the Impact Analysis report, the Admin Tool includes the Interactive Merge Report. This report shows the content merge points and allows you compare the common base content to the existing and incoming content in one display.

Note: When building content for directly processed REQs, notice:

- All output files are writable (no files are Read Only)
- Dynamic and Static documents are exact copies of the original

- Build the Requirements and Content Editor Database
  After you make structural changes to a repository for custom content, for example: adding precedence units, you must build the database so the new precedence units can be displayed (and associated with documents) in the Editor.
