Simplify TOC; older docs pushed a level down; Consolidate debugging Restructured docs.txt. Pulled out older documents into Old Docs. I wish I could add whitespace between documents in the toc. Current order split into groupings: Roundup Features Roundup Features Installing Roundup Upgrading to newer versions of Roundup Reporting Security Issues with Roundup Roundup FAQ User Guide Customising Roundup REST API for Roundup XML-RPC access to Roundup Roundup Reference Roundup Glossary Administration Guide License Acknowledgements Other Docs debugging.txt removed. Its contents replaced a reference in developer.txt. Added olderdocs for: docs/upgrading-history docs/tracker_templates Design Overview <docs/overview> Design (original) <docs/design> docs/developers Notes about the MySQL Database backend <docs/mysql> Notes about the PostgreSQL Database backend <docs/postgresql> Richard Jones implementation notes <docs/implementation> docs/security-history to keep them out of the docs.txt sidebar.
