Unlike Busybox for Android NDK, this module only contains a script exposing Magisk's internal busybox and installing applets. It doesn't carry the actual binary.
You may want to reinstall this module across Magisk upgrades as applets provided may change.
The applets to install can be config by a file /sdcard/busybox-magisk.conf. Place a line of +<applet> to force install an applet. Place a line of -<applet> to skip an applet.(Exclude the angle brackets) Anything else not match the patten will be ignored.
If an applet is not list in the config file, the installer will first search for it in $PATH and install it if not found.
Run busybox --list to get a full list of applets.
