-
-    Keep in mind that this decorator only works for async functions and async generator functions.
-
-    Use this decorator to annotate deployment functions that you want to cache in testing mode.
-
-    There are 3 environment variables that control the behavior of the decorator:
-    - TEST_MODE: set to "true" to enable testing mode
-                (default is "false", should only be set to "true" if you are running tests)
-    - USE_DEPLOYMENT_CACHE: set to "true" to enable cache usage
-    - SAVE_DEPLOYMENT_CACHE: set to "true" to enable cache saving
-
-    The decorator behaves differently in testing and production modes.
-
-    In production mode, the decorator is a no-op.
-    In testing mode, the behavior of the decorator is controlled by the environment variables USE_DEPLOYMENT_CACHE and SAVE_DEPLOYMENT_CACHE.
-
-    If USE_DEPLOYMENT_CACHE is set to "true", the decorator will load the result from the cache if it exists. SAVE_DEPLOYMENT_CACHE is ignored.
-    The decorator takes a hash of the deployment configuration and the function arguments and keyword arguments (args and kwargs) to locate the cache file.
-    If the cache file exists, the decorator will load the result from the cache and return it.
-    If the cache file does not exist, the decorator will try to find the cache file with the closest args and load the result from that cache file
-    (function name and deployment configuration should match exactly, fuzzy matching only applies to args and kwargs).
-
-    If USE_DEPLOYMENT_CACHE is set to "false", the decorator will execute the function and save the result to the cache if SAVE_DEPLOYMENT_CACHE is set to "true".
