+const helpText = `LogWisp: A flexible log transport and processing tool.
+
+Usage: logwisp [options]
+
+Application Control:
+  -c, --config <path>      (string) Path to configuration file (default: logwisp.toml).
+  -h, --help               Display this help message and exit.
+  -v, --version            Display version information and exit.
+  -b, --background         Run LogWisp in the background as a daemon.
+  -q, --quiet              Suppress all console output, including errors.
+      --router             Enable HTTP router mode for multiplexing pipelines.
+
+Runtime Behavior:
+      --disable-status-reporter  Disable the periodic status reporter.
+
+Configuration Sources (Precedence: CLI > Env > File > Defaults):
+  - CLI flags override all other settings.
+  - Environment variables (e.g., LOGWISP_ROUTER=true) override file settings.
+  - TOML configuration file is the primary method for defining pipelines.
+
+Logging ([logging] section or LOGWISP_LOGGING_* env vars):
+  output = "stderr"        (string) Log output: none, stdout, stderr, file, both.
+  level = "info"           (string) Log level: debug, info, warn, error.
+  [logging.file]           Settings for file logging (directory, name, rotation).
+  [logging.console]        Settings for console logging (target, format).
+
+Pipelines ([[pipelines]] array in TOML):
+  Each pipeline defines a complete data flow from sources to sinks.
+  name = "my_pipeline"     (string) Unique name for the pipeline.
+  sources = [...]          (array)  Data inputs (e.g., directory, stdin, http, tcp).
+  sinks = [...]            (array)  Data outputs (e.g., http, tcp, file, stdout, stderr, http_client).
+  filters = [...]          (array)  Optional filters to include/exclude logs based on regex.
+  rate_limit = {...}       (object) Optional rate limiting for the entire pipeline.
+  auth = {...}             (object) Optional authentication for network sinks.
+  format = "json"          (string) Optional output formatter for the pipeline (raw, text, json).
+
+For detailed configuration options, please refer to the documentation.
