-Usage: tool <command> [options] [arguments]
-Example:
-    tool build --portmidi orca
-Commands:
-    build <target>
-        Compiles the livecoding environment or the CLI tool.
-        Targets: orca, cli
-        Output: build/<target>
-    clean
-        Removes build/
-    info
-        Prints information about the detected build environment.
-    help
-        Prints this message and exits.
-Options:
-    -c <name>      Use a specific compiler binary. Default: \$CC, or cc
-    -d             Build with debug features. Output changed to:
-                   build/debug/<target>
-    --harden       Enable compiler safeguards like -fstack-protector.
-                   You should probably do this if you plan to give the
-                   compiled binary to other people.
-    --static       Build static binary.
-    --pie          Enable PIE (ASLR).
-                   Note: --pie and --static cannot be mixed.
-    -s             Print statistics about compile time and binary size.
-    -v             Print important commands as they're executed.
-    -h or --help   Print this message and exit.
-Optional Features:
-    --portmidi     Enable or disable hardware MIDI output support with
-    --no-portmidi  PortMidi. Note: PortMidi has memory leaks and bugs.
-                   Default: disabled.
-    --mouse        Enable or disable mouse features in the livecoding
-    --no-mouse     environment.
-                   Default: enabled.
