+/// \brief      Various integer and bit operations
+///
+/// This file provides macros or functions to do some basic integer and bit
+/// operations.
+///
+/// Endianness related integer operations (XX = 16, 32, or 64; Y = b or l):
+///   - Byte swapping: bswapXX(num)
+///   - Byte order conversions to/from native: convXXYe(num)
+///   - Aligned reads: readXXYe(ptr)
+///   - Aligned writes: writeXXYe(ptr, num)
+///   - Unaligned reads (16/32-bit only): unaligned_readXXYe(ptr)
+///   - Unaligned writes (16/32-bit only): unaligned_writeXXYe(ptr, num)
+///
+/// Since they can macros, the arguments should have no side effects since
+/// they may be evaluated more than once.
+///
+/// \todo       PowerPC and possibly some other architectures support
+///             byte swapping load and store instructions. This file
+///             doesn't take advantage of those instructions.
+///
+/// Bit scan operations for non-zero 32-bit integers:
+///   - Bit scan reverse (find highest non-zero bit): bsr32(num)
+///   - Count leading zeros: clz32(num)
+///   - Count trailing zeros: ctz32(num)
+///   - Bit scan forward (simply an alias for ctz32()): bsf32(num)
+///
+/// The above bit scan operations return 0-31. If num is zero,
+/// the result is undefined.
