Some formatting updates (ran the code through indent) -Erik 2000-02-08 19:58:47 +00:00			`/* vi: set sw=4 ts=4: */`

Patch from Arthur Othieno for style-guide.txt conformance 2003-10-22 10:34:15 +00:00			`/* no options, no getopt */`

Initial revision 1999-10-05 16:24:54 +00:00			`#include <stdio.h>`
Fix header file usage -- there were many unnecessary header files included in busybox.h which slowed compiles. I left only what was needed and then fixed up all the apps to include their own header files. I also fixed naming for pwd.h and grp.h functions. Tested to compile and run with libc5, glibc, and uClibc. -Erik 2001-01-27 08:24:39 +00:00			`#include <stdlib.h>`
It turns out that DODMALLOC was broken when I reorganized busybox.h header file usage before the 0.49 release. To fix it, I had to move the '#include "busybox.h"' to the end of the list of #include files. -Erik 2001-02-20 06:14:08 +00:00			`#include "busybox.h"`

Robert P. Day removed 8 gazillion occurrences of "extern" on function definitions. (That should only be on prototypes.) 2006-03-06 20:47:33 +00:00			`int clear_main(int argc, char **argv)`
