* New flags --encode and --decode can be used to convert between protobuf text
format and binary format from the command-line.
* New flag --descriptor_set_out can be used to write FileDescriptorProtos for
all parsed files directly into a single output file. This is particularly
useful if you wish to parse .proto files from programs written in languages
other than C++: just run protoc as a background process and have it output
a FileDescriptorList, then parse that natively.

symbol defined in the enum type's scope, e.g. if two enum types declared
in the same scope have values with the same name. This is disallowed for

build of libprotobuf.dll. Similarly, release builds must link against
release DLLs.
DLLs and Distribution
=====================
DLLs vs. static linking
=======================
Static linking is now the default for the Protocol Buffer libraries. Due to
issues with Win32's use of a separate heap for each DLL, as well as binary
compatibility issues between different versions of MSVC's STL library, it is
recommended that you use static linkage only. However, it is possible to
build libprotobuf and libprotoc as DLLs if you really want. To do this,
do the following:
1) Open protobuf.sln in MSVC.
2) For each of the projects libprotobuf and libprotoc, do the following:
2a) Right-click the project and choose "properties".
2b) From the side bar, choose "General", under "Configuration Properties".
2c) Change the "Configuration Type" to "Dynamic Library (.dll)".
2d) From the side bar, choose "Preprocessor", under "C/C++".
2e) Add PROTOBUF_USE_DLLS to the list of preprocessor defines.
3) When compiling your project, make sure to #define PROTOBUF_USE_DLLS.
When distributing your software to end users, we strongly recommend that you
do NOT install libprotobuf.dll or libprotoc.dll to any shared location.
Instead, keep these libraries next to your binaries, in your application's
own install directory. C++ makes it very difficult to maintain binary
compatibility between releases, so it is likely that future versions of these
libraries will *not* be usable as drop-in replacements. The only reason we
provide these libraries as DLLs rather than static libs is so that a program
which is itself split into multiple DLLs can safely pass protocol buffer
objects between them.
libraries will *not* be usable as drop-in replacements.
If your project is itself a DLL intended for use by third-party software, we
recommend that you do NOT expose protocol buffer objects in your library's
public interface, and that you statically link protocol buffers into your
library.
TODO(kenton): This sounds kind of scary. Maybe we should only provide static
libraries?
