+# Design Assets Management (for Git projects)

+# -------------------------------------------------------
+#
+# * The `design` function manages the 'design assets' directories for the current project,
+#   including folders such as Backgrounds, Logos, Icons, and Samples. The actual directories are
+#   created in the root design directory, symlinked into the project, and ignored from source control.
+#   This is because we usually don't want to check in design development files such as bitmaps or wav files.
+#   It also gives us the option to sync the root design directory via Dropbox.
+#
+# Examples:
+#
+#    $ design link        # Requires SCM Breeze - Links existing design directories into each of your projects
+#    $ design init        # Creates default directory structure at $root_design_dir/**/ubuntu_config and symlinks into project.
+#                           (Images Backgrounds Logos Icons Mockups Screenshots)
+#    $ design init --av   # Creates extra directories for audio/video assets
+#                           (Images Backgrounds Logos Icons Mockups Screenshots Animations Videos Flash Music Samples)
+#    $ design rm          # Removes any design directories for ubuntu_config
+#    $ design trim        # Trims empty design directories for ubuntu_config
+#
+
+
+# Add ignore rule to .git/info/exclude if not already present
