/* The memory requirements for deflate are (in bytes):

            (1 << (windowBits+2)) +  (1 << (memLevel+9))

 that is: 128K for windowBits=15  +  128K for memLevel = 8  (default values)

 plus a few kilobytes for small objects. For example, if you want to reduce

 the default memory requirements from 256K to 128K, compile with

     make CFLAGS="-O -DMAX_WBITS=14 -DMAX_MEM_LEVEL=7"

 Of course this will generally degrade compression (there's no free lunch).

   The memory requirements for inflate are (in bytes) 1 << windowBits

 that is, 32K for windowBits=15 (default value) plus a few kilobytes

 for small objects.
