How to Edit Core Modules On Acquia Server

The below snippets demonstrate how we can make changes to core and contributed Drupal modules, without write permissions to the files.

From openscholar/drupal-org-core.make:

projects[drupal][patch][] = "https://www.dropbox.com/s/d5dtthvrevphhqe/trace.patch" 
projects[drupal][patch][] = "https://www.dropbox.com/s/6344l5lk9rxxh47/image.inc.patch"

From openscholar/drupal-org.make:

projects[imagemagick][subdir] = "contrib"
projects[imagemagick][version] = 1.0
projects[imagemagick][patch][] = "https://www.dropbox.com/s/c6xgc4jjwc9zcy7/imagemagick.module.patch"
