 ## The difficulty of the problem
 
-This decompiler is a constant work in progress: Python keeps
-changing, and so does its code generation.
+There is no Python decompiler yet, that I know about that will
+decompyle everything. This one probably does the
+best job of *any* Python decompiler. But it is a constant work in progress: Python keeps changing, and so does its code generation.
 
-There is no Python decompiler yet that I know about that will
-decompile everything. Overall, I think this one probably does the best
-job of *any* Python decompiler that handles such a wide range of
-versions.
+I have found bugs in *every* Python decompiler I have tried. Even
+those where authors/maintainers claim that they have used it on
+the entire Python standard library. And I don't mean that
+the program doesn't come out with the same Python source instructions,
+but that the program is *semantically* not equivalent.
 
-But at any given time, there are a number of valid Python bytecode
-files that I know of that will cause problems. See, for example, the
-list in
-[`test/stdlib/runtests.sh`](https://github.com/rocky/python-uncompyle6/blob/master/test/stdlib/runtests.sh).
-
-But I understand: you would the bugs _you_ encounter addressed before
-all the other known bugs.
-
-From my standpoint, the good thing about the bugs listed in
-`runtests.sh` is that each test case is small and isolated to a single
-kind of problem. And I'll tend to fix easier, more isolated cases than
-generic "something's wrong" kinds of bugs where I'd have to do a bit
-of work to figure out what's up, if not use some sort of mind reading,
-make some guesses, and perform some experiments to see if the guesses
-are correct. I can't read minds, nor am I into guessing games; I'd
-rather devote the effort spent instead towards fixing bugs that are
-precisely defined.
-
-And it often turns out that by just fixing the well-defined and
-prescribed cases, the ill-defined amorphous cases as well will get
-handled as well.
-
-In sum, you may need to do some work to have the bug you have found
-handled before the hundreds of other bugs, and things I could be
-doing.
-
-No one is getting paid to work to work on this project, let alone the
-bugs you may have an interest in. If you require decompiling bytecode
-immediately, consider using a decompilation service, listed further
-down in this document.
-
-## Is it really a bug?
-
-
-### Do you have valid bytecode?
-
-As mentioned in README.rst, this project doesn't handle obfuscated
-code. See README.rst for suggestions for how to remove some kinds of
-obfuscation.
-
-Checking if bytecode is valid is pretty simple: disassemble the code.
-Python comes with a disassembly module called `dis`. A prerequisite
-module for this package, `xdis` has a cross-python version
-disassembler called `pydisasm`.
-
-### Semantic equivalence vs. exact source code
-
-Almost all versions of Python can perform some sort of code
-improvement that can't be undone. In earlier versions of Python it is
-rare; in later Python versions, it is more common.
-
-If the code emitted is semantically equivalent, then this isn't a bug.
-
-
-For example the code might be
-
-```
-if a:
-  if b:
-     x = 1
-```
-
-and we might produce:
-
-```
-if a and b:
-  x = 1
-```
-
-These are equivalent. Sometimes
-
-```
-else:
-   if ...
-
-```
-
-may come out as `elif`.
-
-
-As mentioned in the README, It is possible that Python changes what
-you write to be more efficient. For example, for:
-
-
-```
-if True:
-  x = 5
-```
-
-Python will generate code like:
-
-```
-x = 5
-```
-
-So just because the text isn't the same, does not
-necessarily mean there's a bug.
+So it is likely you'll find a mistranslation in decompiling.

 Why this?
 ---------
 
-Ok, I'll say it: this software is amazing. It is more than your
-normal hacky decompiler. Using compiler_ technology, the program
-creates a parse tree of the program from the instructions; nodes at
-the upper levels that look a little like what might come from a Python
-AST. So we can really classify and understand what's going on in
-sections of Python bytecode.
+There were a number of decompyle, uncompile, uncompyle2, uncompyle3
+forks around. All of them came basically from the same code base, and
+almost all of them no were no longer actively maintained. Only one
+handled Python 3, and even there, only 3.2 or 3.3 depending on which
+code is used. This code pulls these together and moves forward. This
+project has the most complete support for Python 3.3 and above. It
+also addresses a number of open issues in the previous forks.
 
-Building on this, another thing that makes this different from other
-CPython bytecode decompilers is the ability to deparse just
-*fragments* of source code and give source-code information around a
-given bytecode offset.
+What makes this different from other CPython bytecode decompilers?: its
+ability to deparse just fragments and give source-code information
+around a given bytecode offset.
 
-I use the tree fragments to deparse fragments of code inside my
-trepan_ debuggers_. For that, bytecode offsets are recorded and
-associated with fragments of the source code. This purpose, although
-compatible with the original intention, is yet a little bit different.
+I use this to deparse fragments of code inside my trepan_
+debuggers_. For that, I need to record text fragments for all
+bytecode offsets (of interest). This purpose although largely
+compatible with the original intention is yet a little bit different.
 See this_ for more information.
 
-Python fragment deparsing given an instruction offset is useful in
-showing stack traces and can be encorporated into any program that
-wants to show a location in more detail than just a line number at
-runtime.  This code can be also used when source-code information does
-not exist and there is just bytecode. Again, my debuggers make use of
-this.

-There were (and still are) a number of decompyle, uncompyle,
-uncompyle2, uncompyle3 forks around. Almost all of them come basically
-from the same code base, and (almost?) all of them are no longer
-actively maintained. One was really good at decompiling Python 1.5-2.3
-or so, another really good at Python 2.7, but that only. Another
-handles Python 3.2 only; another patched that and handled only 3.3.
-You get the idea. This code pulls all of these forks together and
-*moves forward*. There is some serious refactoring and cleanup in this
-code base over those old forks.
-
-This project has the most complete support for Python 3.3 and above
-and the best all-around Python support.
-
-We are serious about testing, and use automated processes to find
-bugs. In the issue trackers for other decompilers, you will find a
-number of bugs we've found along the way. Very few to none of them are
-fixed in the other decompilers.
