+ * 1) All file i/o is done externally to these routines
+ * 2) Routines are symmetrical so inflate can feed into deflate
+ * 3) Routines can be easily integrated into wide range of applications
+ * 4) Routines are very portable, and use only ANSI C
+ * 5) No #defines in inflate.h to conflict with external #defines
+ * 6) No external routines need be called by these routines
+ * 7) Buffers are owned by the calling routine
+ * 8) No static non-constant variables are allowed
+ */
+
+/*
+ * Note that for each call to InflatePutBuffer, there will be
+ * 0 or more calls to (*putbuffer_ptr). All except the last
+ * call to (*putbuffer_ptr) will be with 32768 bytes, although
+ * this behaviour may change in the future. Before InflatePutBuffer
+ * returns, it will have output as much uncompressed data as
+ * is possible.
