+libbb is BusyBox's utility library.  This all used to be in a single file
+(utility.c to be specific).  When I split utility.c up to create libbb, I did
+not carefully fix up the copyright and licensing information.  I'll do that for
+the next release.
+
+For now, justtrust me that a bunch of people have worked on this stuff, 
+and it is all GPL'ed.

+You can set bb_opt_complementaly as string with one or more
+complementaly or incongruously options.
+If sequential founded option haved from this string
+then your incongruously pairs unsets and complementaly make add sets.
+Format:
+one char - option for check,
+chars - complementaly option for add sets.
+- chars - option triggered for unsets.
+~ chars - option incongruously.
+*       - option list, called add_to_list(*ptr_from_usaged, optarg)
+:       - separator.
+Example: du applet can have options "-s" and "-d size"
+If getopt found -s then -d option flag unset or if found -d then -s unset.
+For this result you must set bb_opt_complementaly = "s-d:d-s".
+Result have last option flag only from called arguments.
+Warning! You can check returned flag, pointer to "d:" argument seted
+to own optarg always.
+Example two: cut applet must only one type of list may be specified,
+and -b, -c and -f incongruously option, overwited option is error also.
+You must set bb_opt_complementaly = "b~bcf:c~bcf:f~bcf".
+If called have more one specified, return value have error flag -
+high bite set (0x80000000UL).
+Example three: grep applet can have one or more "-e pattern" arguments.
+You should use bb_getopt_ulflags() as

+ * All-integer version (hey, not everyone has floating point) of
+ * make_human_readable_str, modified from similar code I had written
+ * for busybox several months ago.
+ *
+ * Notes:
+ *   1) I'm using an unsigned long long to hold the product size * block_size,
+ *      as df (which calls this routine) could request a representation of a
+ *      partition size in bytes > max of unsigned long.  If long longs aren't
+ *      available, it would be possible to do what's needed using polynomial
+ *      representations (say, powers of 1024) and manipulating coefficients.
+ *      The base ten "bytes" output could be handled similarly.
+ *
+ *   2) This routine always outputs a decimal point and a tenths digit when 
+ *      display_unit != 0.  Hence, it isn't uncommon for the returned string 
+ *      to have a length of 5 or 6.
+ *
+ *      It might be nice to add a flag to indicate no decimal digits in
+ *      that case.  This could be either an additional parameter, or a
+ *      special value of display_unit.  Such a flag would also be nice for du.
+ *
+ *      Some code to omit the decimal point and tenths digit is sketched out
+ *      and "#if 0"'d below.

+ * While fwrite(), fputc(), fputs(), etc. all set the stream error flag
+ * on failure, the *printf functions are unique in that they can fail
+ * for reasons not related to the actual output itself.  Among the possible
+ * reasons for failure which don't set the streams error indicator,
+ * SUSv3 lists EILSEQ, EINVAL, and ENOMEM.
+ *
+ * In some cases, it would be desireable to have a group of *printf()
+ * functions available that _always_ set the stream error indicator on
+ * failure.  That would allow us to defer error checking until applet
+ * exit.  Unfortunately, there is no standard way of setting a streams
+ * error indicator... even though we can clear it with clearerr().
+ *
+ * Therefore, we have to resort to implementation dependent code.  Feel
+ * free to send patches for stdio implementations where the following
+ * fails.
+ *
+ * NOTE: None of this is threadsafe.  As busybox is a nonthreaded app,
+ *       that isn't currently an issue.
