http://drupal.org/node/74995 => move all issue tracking into a separate module http://cvs.drupal.org/viewcvs/drupal/contributions/modules/ project_issue/ from the intro to the issue:

for all sorts of reasons, we need to move the issue tracking functionality out of project.module and into a separate, smaller, more focused module ("project_issue.module"):

- ability to use project with either project_issue or casetracker - possiblity to use project with an entirely different issue tracking system (see http://groups.drupal.org/node/1047) - keeping the code in smaller pieces so it's easier to work with and understand - developers can more easily focus on either the issue tracking stuff or the project nodes/releases/downloading stuff, depending on their itch reviews and comments, please!

thanks, -derek (dww)
