+
+Busybox is a multicall binary used to provide a minimal subset of 
+POSIX style commands and specialized functions.
+
+It is geared toward 'mini-systems' like boot floppies. Specifically
+it is used in the Debian Rescue/Install system (which caused the 
+original busybox to be made), the Linux Router Project, and others.
+
+As of version 0.20 there is a version number. : )
+Also as of version 0.20, BB is modularized to allow an easy build of
+only the BB parts you need, to reduce binary size.
+
+Edit the file busybox.def.h and comment out the parts you do not need
+using C++ comments (//)
+
+After the build is complete a busybox.links file is generated to allow
+you to easily make the sym/hard links to the busybox binary.
+
+Note the modular system is Makefile based, and purposly very
+simplistic. It does no dependency checking. That is left for you
+to figure out by trial and error.
+
+Please feed patches back to:

+%Description
+BusyBox is a suite of "tiny" Unix utilities in a multi-call binary. It
+provides a pretty complete environment that fits on a floppy or in a
+ROM. Just add "ash" (Keith Almquists tiny Bourne shell clone) and "ae",
+and a kernel and you have a full system. This is used on the Debian
+install disk and in an internet router, and it makes a good environment
+for a "rescue" disk or any small or embedded system.

+ * 3. ls of a symlink to a directory doesn't list directory contents
+ * 4. hidden files can make column width too large
+ * NON-OPTIMAL BEHAVIOUR:
+ * 1. autowidth reads directories twice
+ * 2. if you do a short directory listing without filetype characters

+ * PORTABILITY:

+%Description
+BusyBox is a suite of "tiny" Unix utilities in a multi-call binary. It
+provides a pretty complete environment that fits on a floppy or in a
+ROM. Just add "ash" (Keith Almquists tiny Bourne shell clone) and "ae",
+and a kernel and you have a full system. This is used on the Debian
+install disk and in an internet router, and it makes a good environment
+for a "rescue" disk or any small or embedded system.

+ *
+ * Although I don't really want to add new features to this program to

+ *
+ * KNOWN BUGS:
+ * 1. messy output if you mix files and directories on the command line
+ * 2. ls -l of a directory doesn't give "total <blocks>" header
+ * 3. ls of a symlink to a directory doesn't list directory contents
+ * 4. hidden files can make column width too large
+ * NON-OPTIMAL BEHAVIOUR:
+ * 1. autowidth reads directories twice
+ * 2. if you do a short directory listing without filetype characters
+ *    appended, there's no need to stat each one
+ * PORTABILITY:
+ * 1. requires lstat (BSD) - how do you do it without?
