+""" Example showing how to use a custom function for osxphotos {function} template 
+    to export photos in a folder structure similar to Photos' own structure
+
+    Use:  osxphotos export /path/to/export --directory "{function:/path/to/export_template.py::photos_folders}"
+
+    This will likely export multiple copies of each photo.  If using APFS file system, this should be
+    a non-issue as osxphotos will use copy-on-write so each exported photo doesn't take up additional space
+    unless you edit the photo.
+
+    Thank-you @mkirkland4874 for the inspiration for this example!
+
+    This will produce output similar to this:
+
+Library
+- Photos
+-- {created.year}
+---- {created.mm}
+------ {created.dd}
+- Favorites
+- Hidden
+- Recently Deleted
+- People
+- Places
+- Imports
+Media Types
+- Videos
+- Selfies
+- Portrait
+- Panoramas
+- Time-lapse
+- Slow-mo
+- Bursts
+- Screenshots
+My Albums
+-- Album 1
+-- Album 2
+-- Folder 1
+---- Album 3
+Shared Albums
+-- Shared Album 1
+-- Shared Album 2
