Author: hhubner Date: 2006-02-17 15:05:51 -0600 (Fri, 17 Feb 2006) New Revision: 1840

Added: trunk/projects/lisp-ecoop05/ Removed: trunk/bknr/src/xml-impex/xml-update.lisp trunk/projects/lisp-ecoop/ Modified: trunk/bknr/src/data/object.lisp trunk/bknr/src/web/handlers.lisp trunk/bknr/src/xml-impex/xml-class.lisp trunk/bknr/src/xml-impex/xml-import.lisp trunk/projects/bknr-website/templates/generate-html.xsl trunk/projects/lisp-ecoop05/src/alu-logo.jpg trunk/projects/lisp-ecoop05/src/bknr-logo.png Log: Back out changes in trunk back to 1827 in the hopes to have trunk in a useable state. I'm moving my current project work to the branch xml-class-rework as some of the changes will introduce incompatibilties to the existing and documented xml-class API (among others).
