Appendix A: TWiki File System

Annotated listings of files included in the 01-Sep-2001 TWiki distribution

Overview

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

Directory Structure

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:

twiki list Start-up info
twiki/bin list Perl scripts
twiki/lib list Configuration file, main library, Perl system modules, Plugins
twiki/pub list Public files (e.g. images) and FileAttachments and their RCS histories
