# This file contains an example Flask-User application.

# To keep the example simple, we are applying some unusual techniques:
|
|
# - Placing everything in one file
|
|
# - Using class-based configuration (instead of file-based configuration)
|
|
# - Using string-based templates (instead of file-based templates)
