-Name:Busybox Installer
-Auto Name:BusyBox Free
-Summary:System tools installer
-Description:
-Interface to install one version only of BusyBox (1.21.1) and its symlinks. For
-now, the binary is only for ARM architecture as the others couldn't be built.
-
-BusyBox combines tiny versions of many common UNIX utilities into a single small
-executable. It provides replacements for most of the utilities you usually find
-in GNU fileutils, shellutils, etc. Android comes with a very limited multi-tool
-called Toolbox and sometimes it is crippled even more, so a standard Busybox is
-often needed by root apps that need to do different jobs. If you run a custom
-ROM you probably have most of the applets that you would ever need, though this
-binary has a few more.
-
-The range of applets
-[https://raw2.github.com/linusyang/android-busybox-ndk/master/android_ndk_stericson-like
-available] isn't identical to the upstream version. Therefore, the applet
-manager doesn't have information about all the installed applets.
