_Breakdown of the files included in the 01-Sep-2001 TWiki distribution_

## <a name="0verview"> 0verview </a>

This Appendix contains directory and file listings, with individual file descriptions, for the full 01-Sep-2001 TWiki distribution package.

## <a name="Directory_Structure"> Directory Structure </a>

You can rename the root TWiki directory - `twiki` - to whatever you like by changing it in the `twiki.cfg` configuration file. However, to keep the current installation and future upgrades simple, you should leave the subdirectory structure intact:
