Including Patches in Drupal Contrib Modules

Very occasionally in building a Drupal module (especially for 7.x), you can't actually quite do what you want to do without a change to another module or core. Every effort should be made to avoid that but there are instances that it is truly required and the right method. If on your own site it is pretty easy to document, commit to version control etc - still questionable but doable. However if it is for a public module, it has been problematic at best but there is a way to reduce the pain.
