+
+// 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.

+Changelog:
+2010.11.07 - 0.7-beta1-node
+  - converted it to a node.js compatible module
+
+2010.09.06 - 0.7-beta1
+  - features: vsprintf, support for named placeholders
+  - enhancements: format cache, reduced global namespace pollution
+
+2010.05.22 - 0.6:
+ - reverted to 0.4 and fixed the bug regarding the sign of the number 0
+ Note:
+ Thanks to Raphael Pigulla <raph (at] n3rd [dot) org> (http://www.n3rd.org/)
+ who warned me about a bug in 0.5, I discovered that the last update was
+ a regress. I appologize for that.
+
+2010.05.09 - 0.5:
+ - bug fix: 0 is now preceeded with a + sign
+ - bug fix: the sign was not at the right position on padded results (Kamal Abdali)
+ - switched from GPL to BSD license
+
+2007.10.21 - 0.4:
+ - unit test and patch (David Baird)
+
+2007.09.17 - 0.3:
+ - bug fix: no longer throws exception on empty paramenters (Hans Pufal)
+
+2007.09.11 - 0.2:
+ - feature: added argument swapping
+
+2007.04.03 - 0.1:
+ - initial release
