Changes you will need to make: * In your environment.rb, you will need to update references to a few files per environment.rb.tmpl * In your environment.rb, you will need to specify the local time zone of the computer that is running your Tracks install. Other notes on my changes: * Modified our code to take advantage of Rails 2.1's slick time zone support. * Upgraded will_paginate for compatibility * Hacked the Selenium on Rails plugin, which has not been updated in some time and does not support Rails 2.1 * Verified that all tests pass on my machine, including Selenium tests -- I'd like confirmation from others, too.

# Implements the logic behind the rake tasks for annotations like

# the filename is not stored.
|

|
|
# Annotations are looked for in comments and modulus whitespace they have to
|
|
# start with the tag optionally followed by a colon. Everything up to the end
|
|
# of the line (or closing ERb comment tag) is considered to be their text.
