WebCFG is an easy-to-install easy-to-use platform independent generic web front end for editing local/remote based text files (e.g. system configuration files simply in your web browser - there is no need for shell commands or Unix editors anymore. After modification is done, WebCFG executes local / remote commands/scripts forcing processing the new configuration (e.g. restart / reload a dependant service). Injecting special comment-tags like '# @WC tab / radiobuttons / combobox / textbox /...' to the text file will optimize and beautify the presentation in the web frontend for you or your customers. WebCFG includes an example for SpamAssassin managing white- and blacklists.
