+
+Summary
+=======
+
+psutil (process and system utilities) is a cross-platform library for
+retrieving information on **running processes** and **system utilization**
+(CPU, memory, disks, network, sensors) in Python.
+It is useful mainly for **system monitoring**, **profiling and limiting process
+resources** and **management of running processes**.
+It implements many functionalities offered by classic UNIX command line tools
+such as *ps, top, iotop, lsof, netstat, ifconfig, free* and others.
+psutil currently supports the following platforms:
+
+- **Linux**
+- **Windows**
+- **macOS**
+- **FreeBSD, OpenBSD**, **NetBSD**
+- **Sun Solaris**
+- **AIX**
+
+...both **32-bit** and **64-bit** architectures. Supported Python versions are **2.6**, **2.7** and **3.4+**. `PyPy3 <http://pypy.org/>`__ is also known to work.

+Tests for detecting function memory leaks (typically the ones
+implemented in C). It does so by calling a function many times and
+checking whether process memory usage keeps increasing between
+calls or over time.
+Note that this may produce false positives (especially on Windows
+for some reason).
+PyPy appears to be completely unstable for this framework, probably
+because of how its JIT handles memory, so tests are skipped.

+Notes about unicode handling in psutil
+======================================
+
+Starting from version 5.3.0 psutil adds unicode support, see:
+https://github.com/giampaolo/psutil/issues/1040
+The notes below apply to *any* API returning a string such as
+process exe(), cwd() or username():
+
+* all strings are encoded by using the OS filesystem encoding
+  (sys.getfilesystemencoding()) which varies depending on the platform
+  (e.g. "UTF-8" on macOS, "mbcs" on Win)
+* no API call is supposed to crash with UnicodeDecodeError
+* instead, in case of badly encoded data returned by the OS, the
+  following error handlers are used to replace the corrupted characters in
+  the string:
+    * Python 3: sys.getfilesystemencodeerrors() (PY 3.6+) or
+      "surrogatescape" on POSIX and "replace" on Windows
+    * Python 2: "replace"
+* on Python 2 all APIs return bytes (str type), never unicode
+* on Python 2, you can go back to unicode by doing:
+
+    >>> unicode(p.exe(), sys.getdefaultencoding(), errors="replace")
+
+For a detailed explanation of how psutil handles unicode see #1040.
+
+Tests
+=====
+
+List of APIs returning or dealing with a string:
+('not tested' means they are not tested to deal with non-ASCII strings):
+
+* Process.cmdline()
+* Process.connections('unix')
+* Process.cwd()
+* Process.environ()
+* Process.exe()
+* Process.memory_maps()
+* Process.name()
+* Process.open_files()
+* Process.username()             (not tested)
+
+* disk_io_counters()             (not tested)
+* disk_partitions()              (not tested)
+* disk_usage(str)
+* net_connections('unix')
+* net_if_addrs()                 (not tested)
+* net_if_stats()                 (not tested)
+* net_io_counters()              (not tested)
+* sensors_fans()                 (not tested)
+* sensors_temperatures()         (not tested)
+* users()                        (not tested)
+
+* WindowsService.binpath()       (not tested)
+* WindowsService.description()   (not tested)
+* WindowsService.display_name()  (not tested)
+* WindowsService.name()          (not tested)
+* WindowsService.status()        (not tested)
+* WindowsService.username()      (not tested)
+
+In here we create a unicode path with a funky non-ASCII name and (where
+possible) make psutil return it back (e.g. on name(), exe(), open_files(),
+etc.) and make sure that:
+
+* psutil never crashes with UnicodeDecodeError
+* the returned path matches

+Intro
+=====
+
+I would like to recognize some of the people who have been instrumental in the
+development of psutil. I'm sure I'm forgetting somebody (feel free to email me)
+but here is a short list. It's modeled after the Linux CREDITS file where the
+fields are: name (N), e-mail (E), website (W), country (C), description (D),
+(I) issues. Issue tracker is at https://github.com/giampaolo/psutil/issues).
+A big thanks to all of you.

+Install pip
+===========
+
+pip is the easiest way to install psutil. It is shipped by default with Python
+2.7.9+ and 3.4+. For other Python versions you can install it manually.
+On Linux or via wget::
+
+    wget https://bootstrap.pypa.io/get-pip.py -O - | python
+
+On macOS or via curl::
+
+    python < <(curl -s https://bootstrap.pypa.io/get-pip.py)
+
+On Windows, `download pip <https://pip.pypa.io/en/latest/installing/>`__, open
+cmd.exe and install it::
+
+    C:\Python27\python.exe get-pip.py
+
+Permission issues (UNIX)
+========================
+
+The commands below assume you're running as root.
+If you aren't or you bump into permission errors you can either install psutil
+for your user only::
+
+    pip3 install --user psutil
+
+...or prepend ``sudo`` and install it globally, e.g.::
+
+    sudo pip3 install psutil
+
+Linux
+=====
+
+Ubuntu / Debian::
+
+    sudo apt-get install gcc python3-dev
+    pip3 install psutil
+
+RedHat / CentOS::
+
+    sudo yum install gcc python3-devel
+    pip3 install psutil
+
+If you're on Python 2 use ``python-dev`` instead.
+
+macOS
+=====
+
+Install `Xcode <https://developer.apple.com/downloads/?name=Xcode>`__ then run::
+
+    pip3 install psutil
+
+Windows
+=======
+
+Open a cmd.exe shell and run::
+
+    python3 -m pip install psutil
+
+This assumes "python" is in your PATH. If not, specify the full python.exe
+path.
+
+In order to compile psutil from sources you'll need **Visual Studio** (Mingw32
+is not supported).
+This  `blog post <https://blog.ionelmc.ro/2014/12/21/compiling-python-extensions-on-windows/>`__
+provides numerous info on how to properly set up VS. The needed VS versions are:
+
+* Python 2.6, 2.7: `VS-2008 <http://www.microsoft.com/en-us/download/details.aspx?id=44266>`__
+* Python 3.4: `VS-2010 <http://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express>`__
+* Python 3.5+: `VS-2015 <http://www.visualstudio.com/en-au/news/vs2015-preview-vs>`__
+
+Compiling 64 bit versions of Python 2.6 and 2.7 with VS 2008 requires
+`Windows SDK and .NET Framework 3.5 SP1 <https://www.microsoft.com/en-us/download/details.aspx?id=3138>`__.
+Once installed run `vcvars64.bat`
+(see `here <http://stackoverflow.com/questions/11072521/>`__).
+Once VS is setup open a cmd.exe shell, cd into psutil directory and run::
+
+    python3 setup.py build
+    python3 setup.py install
+
+FreeBSD
+=======
+
+::
+
+    pkg install python3 gcc
+    python -m pip3 install psutil
+
+OpenBSD
+=======
+
+::
+
+    export PKG_PATH=http://ftp.eu.openbsd.org/pub/OpenBSD/`uname -r`/packages/`uname -m`/
+    pkg_add -v python gcc
+    python3 -m pip install psutil
+
+NetBSD
+======
+
+::
+
+    export PKG_PATH="ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/`uname -m`/`uname -r`/All"
+    pkg_add -v pkgin
+    pkgin install python3 gcc
+    python3 -m pip install psutil
+
+Solaris
+=======
+
+If ``cc`` compiler is not installed create a symlink to ``gcc``::
+
+    sudo ln -s /usr/bin/gcc /usr/local/bin/cc
+
+Install::
+
+    pkg install gcc
+    python3 -m pip install psutil
+
+Install from sources
+====================
+
+::
+
+    git clone https://github.com/giampaolo/psutil.git
+    cd psutil
+    python3 setup.py install
+
+Testing installation
+====================
+
+::
+
+    python3 -m psutil.tests

+        Summary
+        =======
+        
+        psutil (process and system utilities) is a cross-platform library for
+        retrieving information on **running processes** and **system utilization**
+        (CPU, memory, disks, network, sensors) in Python.
+        It is useful mainly for **system monitoring**, **profiling and limiting process
+        resources** and **management of running processes**.
+        It implements many functionalities offered by classic UNIX command line tools
+        such as *ps, top, iotop, lsof, netstat, ifconfig, free* and others.
+        psutil currently supports the following platforms:
+        
+        - **Linux**
+        - **Windows**
+        - **macOS**
+        - **FreeBSD, OpenBSD**, **NetBSD**
+        - **Sun Solaris**
+        - **AIX**
+        
+        ...both **32-bit** and **64-bit** architectures. Supported Python versions are **2.6**, **2.7** and **3.4+**. `PyPy3 <http://pypy.org/>`__ is also known to work.
+

+Summary
+=======
+
+psutil (process and system utilities) is a cross-platform library for
+retrieving information on **running processes** and **system utilization**
+(CPU, memory, disks, network, sensors) in Python.
+It is useful mainly for **system monitoring**, **profiling and limiting process
+resources** and **management of running processes**.
+It implements many functionalities offered by classic UNIX command line tools
+such as *ps, top, iotop, lsof, netstat, ifconfig, free* and others.
+psutil currently supports the following platforms:
+
+- **Linux**
+- **Windows**
+- **macOS**
+- **FreeBSD, OpenBSD**, **NetBSD**
+- **Sun Solaris**
+- **AIX**
+
+...both **32-bit** and **64-bit** architectures. Supported Python versions are **2.6**, **2.7** and **3.4+**. `PyPy3 <http://pypy.org/>`__ is also known to work.

+rem - Visual studio 2010 for Python 3.4+
+rem ...therefore it might not work on your Windows installation.
+rem
+rem By default C:\Python27\python.exe is used.
+rem To compile for a specific Python version run:
+rem     set PYTHON=C:\Python34\python.exe & make.bat build
+rem
+rem To use a different test script:
+rem      set PYTHON=C:\Python34\python.exe & set TSCRIPT=foo.py & make.bat test
