There is a contributed module for assisting with code review. To use this module you must complete the following steps:

• Install the Coder module.
• Click on the "Code Review" link in your navigation menu.
• Scroll down to "Select Specific Modules".
• Select the module you wish to review, and click the "Submit" button.

As an alternative to starting from the Code Review link in navigation, you can also review a particular module's code by clicking on the link on the Modules admin screen.

The Coder module also comes with a command-line script called "Coder Format", which will not only check your files for standards compliance, but fix them. Use with care!
