/**
 * short_types - shorter names for standard integer types
 *
 * "C is a Spartan language, and so should your naming be."
 *	-- Linus Torvalds
 *
 * The short_types header provides for convenient abbreviations for the
 * posixly-damned uint32_t types.  If ccan/endian/endian.h is included,
 * it also provides be32/le32 for explicitly annotating types of specific
 * endian.
 *
 * Include this header, if only to stop people using these identifiers
 * for other things!
 *
 * Example:
 *	#include <stdint.h>
 *	#include <string.h>
 *	#include <stdio.h>
 *	#include <ccan/short_types/short_types.h>
 *	
 *	// Print nonsensical numerical comparison of POSIX vs. short_types. 
 *	#define stringify_1(x)	#x
 *	#define stringify(x)	stringify_1(x)
 *	
 *	static void evaluate(size_t size, const char *posix, const char *sht,
 *			     unsigned int *posix_total, unsigned int *sht_total,
 *			     unsigned int *size_total)
 *	{
 *		printf("\t%ssigned %s: POSIX %zu%%, short %zu%%\n",
 *		       sht[0] == 'u' ? "un" : "",
 *		       sht+1,
 *		       strlen(posix)*100 / size,
 *		       strlen(sht)*100 / size);
 *		*posix_total += strlen(posix);
 *		*sht_total += strlen(sht);
 *		*size_total += size;
 *	}
 *
 *	#define EVALUATE(psx, short, pt, st, t)				\
 *		evaluate(sizeof(psx), stringify(psx), stringify(sht), pt, st, t)
 *
 *	int main(void)
 *	{
 *		unsigned int posix_total = 0, sht_total = 0, size_total = 0;
 *
 *		printf("Comparing size of type vs size of name:\n");
 *
 *		EVALUATE(uint8_t, u8, &posix_total, &sht_total, &size_total);
 *		EVALUATE(int8_t, s8, &posix_total, &sht_total, &size_total);
 *		EVALUATE(uint16_t, u16, &posix_total, &sht_total, &size_total);
 *		EVALUATE(int16_t, s16, &posix_total, &sht_total, &size_total);
 *		EVALUATE(uint32_t, u32, &posix_total, &sht_total, &size_total);
 *		EVALUATE(int32_t, s32, &posix_total, &sht_total, &size_total);
 *		EVALUATE(uint64_t, u64, &posix_total, &sht_total, &size_total);
 *		EVALUATE(int64_t, s64, &posix_total, &sht_total, &size_total);
 *
 *		printf("Conclusion:\n"
 *		       "\tPOSIX is %u%% LESS efficient than binary.\n"
 *		       "\tshort_types.h is %u%% MORE efficient than binary.\n",
 *		       (posix_total - size_total) * 100 / size_total,
 *		       (size_total - sht_total) * 100 / size_total);
 *		return 0;
