+"""Module to convert log levels between Abseil Python, C++, and Python standard.
+
+This converter has to convert (best effort) between three different
+logging level schemes:
+  cpp      = The C++ logging level scheme used in Abseil C++.
+  absl     = The absl.logging level scheme used in Abseil Python.
+  standard = The python standard library logging level scheme.
+
+Here is a handy ascii chart for easy mental mapping.
+
+  LEVEL    | cpp |  absl  | standard |
+  ---------+-----+--------+----------+
+  DEBUG    |  0  |    1   |    10    |
+  INFO     |  0  |    0   |    20    |
+  WARNING  |  1  |   -1   |    30    |
+  ERROR    |  2  |   -2   |    40    |
+  CRITICAL |  3  |   -3   |    50    |
+  FATAL    |  3  |   -3   |    50    |
+
+Note: standard logging CRITICAL is mapped to absl/cpp FATAL.
+However, only CRITICAL logs from the absl logger (or absl.logging.fatal) will
+terminate the program. CRITICAL logs from non-absl loggers are treated as
+error logs with a message prefix "CRITICAL - ".
+
+Converting from standard to absl or cpp is a lossy conversion.
+Converting back to standard will lose granularity.  For this reason,
+users should always try to convert to standard, the richest
+representation, before manipulating the levels, and then only to cpp
+or absl if those level schemes are absolutely necessary.
