Jim Berry on the Grammar Parser and Coder modules
Jim Berry (aka solotandem) is the father of Jimmy "Boombatower" Berry and talks about the Grammar Parser module, which is used in the API module and Coder Upgrade portion of the Coder module. Berry is also the author of the Deadwood module to help upgrade modules from Drupal 5 to Drupal 6, and this functionality has been improved with the Grammar Parser and migrated into the Coder upgrade module for upgrading modules from Drupal 6 to Drupal 7.
