+Command: $0 [--debug] [--raw-output] <subcommand> [args] ...
+Command line client for controlling Bambu Labs 3D printers.
+
+This script relies on a configuration file located at $CONFIG_PATH.
+The configuration file should be a Bash script that sets the following variables:
+
+BAMBU_IP
+BAMBU_SERIAL
+BAMBU_ACCESS_CODE
+
+Subcommands:
+    help        - Print this help message
+    status      - Display current status of the printer
+    file
+         ls [--list-only] [--file] [path]
+                - List <path> on the printer's SD card.
+                  If "--list-only" is specified, only print out the names
+                  of files without metadata (timestamp, etc.).
+                  If "--file" is specified, then <path> is assumed
+                  to be a file, and it is listed on its own instead of
+                  trying to list its children.
+         get [-o|--output <output_directory>] <remote_file>
+                - Download <remote_file> to <output_directory> (\$PWD by default)
+         put <local_file> <remote_directory>
+                - Upload <local_file> to <remote_directory>
+         rm [-r|--recursive] <path>
+                - Delete the remote <path> on the printer.
+                  If "-r" is specified, assume <path> is a directory and
+                  delete all of its children, including itself.
+    print
+         start [--timelapse] [--no-bed-leveling] [--no-vibration-calibration]
+               [--flow-calibration] <remote_file>
+                - Start a print job with <remote_file>. Only single-plate 3mf
+                  files are supported.
+         pause|resume|stop
+                - As names suggest.
+         check
+                - Check the current print status from the printer and output
+                  any potential error codes.
