-## Custom Logger
-
-We found the `logging` module from the standard Python library hard to configure when other subprojects or libraries also use it. Additionally, we wanted to have an automatic archiving functionality.
-
-Hence, this class is a simple reimplementation of the logging module's core features.
-
-```python
-from tum_esm_utils.logger import Logger
-
-my_logger = Logger(
-    origin = "my_logger",
-    logfile_directory = "/tmp/logs"
-)
-```
-
-The log lines of the last hour can be found in `/tmp/logs/current-logs.log`. All older log lines can be found in `/tmp/logs/archive/YYYYMMDD.log` (`/tmp ...` is used in the example code above).
-
-Regular log lines (debug, info, warning, error):
-
-```python
-my_logger.debug("hello")
-my_logger.info("hello")
-my_logger.warning("hello")
-my_logger.error("hello")
-```
-
-```log
-time UTC±X - origin - level - message
-```
-
-You can give the more details to each log type:
-
-```python
-my_logger.debug("hello", details="some elaborate details on what happened")
-```
-
-```log
-time UTC±X - origin - DEBUG - hello
---- details: ---------------------------
-some elaborate details on what happened
-----------------------------------------
-```
-
-Exception logging:
-
-```python
-try:
-    30 / 0
-except Exception:
-    my_logger.exception(
-        label="custom label",
-        details="some elaborate details on what happened"
-    )
-```
-
-```log
-time UTC±X - origin - EXCEPTION - custom label, ZeroDivisionError: division by zero
---- details: ---------------------------
-some elaborate details on what happened
---- traceback: -------------------------
-...
-----------------------------------------

 ## Strict Path Validation with Pydantic
 
 Pydantic has a lot of field validators (number must be greater equal, etc.),
