-
-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.
