VIRTUALENV(1)															     VIRTUALENV(1)

NAME

       virtualenv - create virtual Python instances

SYNOPSIS

       virtualenv [options...] [destination-directory]

DESCRIPTION

       virtualenv creates virtual Python executables, each of which can have its own set of installed modules. Programs that require different
       versions of modules or sets of modules that may be incompatible with others to be installed on the same system without conflicts.

       The result is a directory containing its own Python executables (in DIR/bin/pythonVER and DIR/bin/python) and its own module directory
       containing the standard library as installed by the system.  Additional modules may be installed via setuptools, as invoked from the binary
       directory (DIR/bin/easy_install). The system's site-packages directories will not be available by default, but can be made visible with the
       --system-site-packages option. They can then be overridden with locally-installed modules.

       In addition, a shell script called "activate" will be installed in the bin directory. If sourced, this will cause normal invocations of the
       Python executable to use the virtual environment.

       By running the virtualenv command explicitly under the desired Python interpreter, the user can control which version of Python is created
       in the virtual environment.

OPTIONS

       -h, --help
	   Show summary of options.

       --version
	   Show the version of the program.

       -v, --verbose
	   Be more verbose.

       -q, --quiet
	   Be less verbose; suppress unimportant output.

       --clear
	   Clear out a previously-created virtual Python instance in this location before creating a new one.

       -p PYTHON_EXE,--python=PYTHON_EXE
	   The Python interpreter to use to create the new environment.

       --no-site-packages
	   Ignored (the default).  Don't give access to the global site-packages modules to the virtual environment.

       --system-site-packages
	   Give access to the global site-packages modules to the virtual environment.

       --unzip-setuptools
	   Unzip Setuptools or Distribute when installing it.

       --relocatable
	   Make an EXISTING virtualenv environment relocatable.

       --distribute
	   Ignored.  Distribute is used by default.  See --setuptools to use Setuptools instead of Distribute.

       --setuptools
	   Use Setuptools instead of Distribute. Set environ variable VIRTUALENV_SETUPTOOLS to make it the default.

       --extra-search-dir=SEARCH_DIRS
	   Directory to search for setuptools/distribute/pip distributions in.	Can be specified multiple times.

       --never-download
	   Never download anything from the network.  Instead, fail if local distributions of setuptools/distribute/pip are not present.

       --prompt==PROMPT
	   Provides an alternative prompt prefix for this environment.

NAME

       dh_python - calculates Python dependencies and adds postinst and prerm Python scripts (deprecated)

SYNOPSIS

       dh_python [debhelperoptions] [-n] [-V version] [moduledirs...]

DESCRIPTION

       Note: This program is deprecated. You should use dh_python2 instead.  This program will do nothing if debian/pycompat or a Python-Version
       control file field exists.

       dh_python is a debhelper program that is responsible for generating the ${python:Depends} substitutions and adding them to substvars files.
       It will also add a postinst and a prerm script if required.

       The program will look at Python scripts and modules in your package, and will use this information to generate a dependency on python, with
       the current major version, or on pythonX.Y if your scripts or modules need a specific python version. The dependency will be substituted
       into your package's control file wherever you place the token ${python:Depends}.

       If some modules need to be byte-compiled at install time, appropriate postinst and prerm scripts will be generated. If already byte-
       compiled modules are found, they are removed.

       If you use this program, your package should build-depend on python.

OPTIONS

       module dirs
	   If your package installs Python modules in non-standard directories, you can make dh_python check those directories by passing their
	   names on the command line. By default, it will check /usr/lib/site-python, /usr/lib/$PACKAGE, /usr/share/$PACKAGE,
	   /usr/lib/games/$PACKAGE, /usr/share/games/$PACKAGE and /usr/lib/python?.?/site-packages.

	   Note: only /usr/lib/site-python, /usr/lib/python?.?/site-packages and the extra names on the command line are searched for binary (.so)
	   modules.

       -V version
	   If the .py files your package ships are meant to be used by a specific pythonX.Y version, you can use this option to specify the
	   desired version, such as 2.3. Do not use if you ship modules in /usr/lib/site-python.

       -n, --noscripts
	   Do not modify postinst/prerm scripts.
