Announcing a new and quite simple module for Chomskyan Drupallers: phpSyntaxTree. It's just a wrapper to the nice phpSyntaxTree app/library provided by André & Mei Eisenbach. Simple to use, the wrapper works as an input filter, using the syntax: [tree]...a tree in bracket notation...[/tree]
That's good news for those who are waiting for the complete set of contributed modules to start new projects using Drupal 6. Panels project has released its D6 compatible version. It's an alpha version yet, but that's a good start, anyway. See more at the project page: http://drupal.org/project/panels
