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

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"`

Don't use strings directly in calls to usage(). This is in preparation for their extraction to a separate file. 2000-07-14 23:28:47 +00:00			`extern int length_main(int argc, char **argv)`

This patch, put together by Manuel Novoa III, is a merge of work done by Evin Robertson (bug#1105) and work from Manuel to make usage messages occupy less space and simplify how usage messages are displayed. 2001-02-14 21:23:06 +00:00			`show_usage();`
More Doc updates. cmdedit and more termio fixes. 2000-04-21 01:26:49 +00:00			`printf("%lu\n", (long)strlen(argv[1]));`
Stop using TRUE and FALSE for exit status. 2000-12-01 02:55:13 +00:00			`return EXIT_SUCCESS;`
