+"""
+Source engine log filter for Umbrella (TF2, GMod, CS2, etc.)
+
+Strips noisy lines that flood the output without useful information:
+  - server_cvar changes (spammy on startup and plugin reloads)
+  - Bot navigation stuck/path_goal spam
+  - Empty lines
+
+Strips the "L MM/DD/YYYY - HH:MM:SS: " timestamp prefix so output
+is shorter in the CLI. The umbrella daemon log already has its own
+timestamps if you need them.
+
+Install: /usr/lib/umbrella/filters/source.py
+Unit YAML: log_filter: /usr/lib/umbrella/filters/source.py
