This directory contains the Python Protocol Buffers runtime library.

Normally, this directory comes as part of the protobuf package, available
from:

  http://code.google.com/p/protobuf

The complete package includes the C++ source code, which includes the
Protocol Compiler (protoc).  If you downloaded this package from PyPI
or some other Python-specific source, you may have received only the
Python part of the code.  In this case, you will need to obtain the
Protocol Compiler from some other source before you can use this
package.

Development Warning
===================

The Python implementation of Protocol Buffers is not as mature as the C++
and Java implementations.  It may be more buggy, and it is known to be
pretty slow at this time.  If you would like to help fix these issues,
join the Protocol Buffers discussion list and let us know!

Installation
============

1) Make sure you have Python 2.4 or newer.  If in doubt, run:

     $ python -V

2) If you do not have setuptools installed, note that it will be
   downloaded and installed automatically as soon as you run setup.py.
   If you would rather install it manually, you may do so by following
   the instructions on this page:

     http://peak.telecommunity.com/DevCenter/EasyInstall#installation-instructions

3) Build the C++ code, or install a binary distribution of protoc.  If
   you install a binary distribution, make sure that it is the same
   version as this package.  If in doubt, run:

     $ protoc --version

4) Run the tests:

     $ python setup.py test

   If some tests fail, this library may not work correctly on your
   system.  Continue at your own risk.

   Please note that there is a known problem with some versions of
   Python on Cygwin which causes the tests to fail after printing the
   error:  "sem_init: Resource temporarily unavailable".  This appears
   to be a bug either in Cygwin or in Python:
     http://www.cygwin.com/ml/cygwin/2005-07/msg01378.html
   We do not know if or when it might me fixed.  We also do not know
   how likely it is that this bug will affect users in practice.

5) Install:

     $ python setup.py install

   This step may require superuser privileges.

Usage
=====

The complete documentation for Protocol Buffers is available via the
web at:

  http://code.google.com/apis/protocolbuffers/
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
