+.Synopsis
+Activate a Python virtual environment for the current PowerShell session.
+
+.Description
+Pushes the python executable for a virtual environment to the front of the
+$Env:PATH environment variable and sets the prompt to signify that you are
+in a Python virtual environment. Makes use of the command line switches as
+well as the `pyvenv.cfg` file values present in the virtual environment.
+
+.Parameter VenvDir
+Path to the directory that contains the virtual environment to activate. The
+default value for this is the parent of the directory that the Activate.ps1
+script is located within.
+
+.Parameter Prompt
+The prompt prefix to display when this virtual environment is activated. By
+default, this prompt is the name of the virtual environment folder (VenvDir)
+surrounded by parentheses and followed by a single space (ie. '(.venv) ').
+
+.Example
+Activate.ps1
+Activates the Python virtual environment that contains the Activate.ps1 script.
+
+.Example
+Activate.ps1 -Verbose
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and shows extra information about the activation as it executes.
+
+.Example
+Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
+Activates the Python virtual environment located in the specified location.
+
+.Example
+Activate.ps1 -Prompt "MyPython"
+Activates the Python virtual environment that contains the Activate.ps1 script,
+and prefixes the current prompt with the specified string (surrounded in
+parentheses) while the virtual environment is active.
+
+.Notes
+On Windows, it may be required to enable this Activate.ps1 script by setting the
+execution policy for the user. You can do this by issuing the following PowerShell
+command:
+
+PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+
+The Cython language makes writing C extensions for the Python language as
+easy as Python itself.  Cython is a source code translator based on Pyrex_,
+but supports more cutting edge functionality and optimizations.
+
+The Cython language is a superset of the Python language (almost all Python
+code is also valid Cython code), but Cython additionally supports optional
+static typing to natively call C functions, operate with C++ classes and
+declare fast C types on variables and class attributes.  This allows the
+compiler to generate very efficient C code from Cython code.
+
+This makes Cython the ideal language for writing glue code for external
+C/C++ libraries, and for fast C modules that speed up the execution of
+Python code.
+
+Note that for one-time builds, e.g. for CI/testing, on platforms that are not
+covered by one of the wheel packages provided on PyPI *and* the pure Python wheel
+that we provide is not used, it is substantially faster than a full source build
+to install an uncompiled (slower) version of Cython with::
+
+    pip install Cython --install-option="--no-cython-compile"
+

+            ...
+

+        Note that the cell itself needs to take care of establishing a suitable

+

+Cython (http://cython.org) is a compiler for code written in the
+Cython language.  Cython is based on Pyrex by Greg Ewing.
+
+Usage: cython [options] sourcefile.{pyx,py} ...
+
+Options:
+  -V, --version                  Display version number of cython compiler
+  -l, --create-listing           Write error messages to a listing file
+  -I, --include-dir <directory>  Search for include files in named directory
+                                 (multiple include directories are allowed).
+  -o, --output-file <filename>   Specify name of generated C file
+  -t, --timestamps               Only compile newer source files
+  -f, --force                    Compile all source files (overrides implied -t)
+  -v, --verbose                  Be verbose, print file names on multiple compilation
+  -p, --embed-positions          If specified, the positions in Cython files of each
+                                 function definition is embedded in its docstring.
+  --cleanup <level>              Release interned objects on python exit, for memory debugging.
+                                 Level indicates aggressiveness, default 0 releases nothing.
+  -w, --working <directory>      Sets the working directory for Cython (the directory modules
+                                 are searched from)
+  --gdb                          Output debug information for cygdb
+  --gdb-outdir <directory>       Specify gdb debug information output directory. Implies --gdb.
+
+  -D, --no-docstrings            Strip docstrings from the compiled module.
+  -a, --annotate                 Produce a colorized HTML version of the source.
+  --annotate-coverage <cov.xml>  Annotate and include coverage information from cov.xml.
+  --line-directives              Produce #line directives pointing to the .pyx source
+  --cplus                        Output a C++ rather than C file.
+  --embed[=<method_name>]        Generate a main() function that embeds the Python interpreter.
+  -2                             Compile based on Python-2 syntax and code semantics.
+  -3                             Compile based on Python-3 syntax and code semantics.
+  --3str                         Compile based on Python-3 syntax and code semantics without
+                                 assuming unicode by default for string literals under Python 2.
+  --lenient                      Change some compile time errors to runtime errors to
+                                 improve Python compatibility
+  --capi-reexport-cincludes      Add cincluded headers to any auto-generated header files.
+  --fast-fail                    Abort the compilation on the first error
+  --warning-errors, -Werror      Make all warnings into errors
+  --warning-extra, -Wextra       Enable extra warnings
+  -X, --directive <name>=<value>[,<name=value,...] Overrides a compiler directive
+  -E, --compile-time-env name=value[,<name=value,...] Provides compile time env like DEF would do.
+  --module-name                  Fully qualified module name. If not given, it is deduced from the
+                                 import path if source file is in a package, or equals the
+                                 filename otherwise.
+  -M, --depfile                  Produce depfiles for the sources
+"""
+
+
+# The following experimental options are supported only on MacOSX:
+#  -C, --compile    Compile generated .c file to .o file
+#  --link           Link .o file to produce extension module (implies -C)
+#  -+, --cplus      Use C++ compiler for compiling and linking
