+AVUtil
+======
+libavutil is a small lightweight library of generally usefull functions
+it is not a library of code which is needed by both libavcodec and libavformat
+
+
+Overview:
+=========
+adler32.c adler32 checksum
+aes.c AES encryption and decryption
+fifo.c resizeable first in first out buffer
+intfloat_readwrite.c portable reading and writing of floating point values
+log.c "printf" with context and level
+md5.c MD5 Message-Digest Algorithm
+rational.c code to perform exact calculation with rational numbers
+tree.c generic AVL tree
+crc.c generic CRC checksumming code
+integer.c 128bit integer math
+lls.c
+mathematics.c greatest common divisor, integer sqrt, integer log2, ...
+mem.c memory allocation routines with guranteed alignment
+softfloat.c
+
+Headers:
+bswap.h big/little/native endian conversation code
+x86_cpu.h a few usefull macros for unifying x86-64 and x86-32 code
+avutil.h
+common.h
+intreadwrite.h reading and writing of unaligned big, little and native endian integers
+
+
+Goals:
+======
+* Modular (few interdependancies and the possibility of disabling individual parts during ./configure)
+* Small (source and object)
+* Efficient (low cpu and memory usage)
+* Usefull (avoid useless features almost noone needs)
