NAME

       getting started - numm installation and usage

SYNOPSIS

       numm-run FILE
       import numm

DESCRIPTION

       numm is a python library -- the bastard child of Processing.org and MATLAB, if you will -- that fuses python, numpy, and gstreamer together
       to create a numerical-computing environment for multimedia generation, analysis, and interaction.

   Installation
       A Debian package is provided for ease of installation on Debian and derivative operating systems, such as Ubuntu; we recommend you  abandon
       alternative systems and install Debian, but in the interim direct your attention to  virtualization software such as VirtualBox.

       The following command downloads and installs numm:
       % wget http://numm.org/numm/releases/python-numm_0.1-1_all.deb
       % sudo dpkg -i python-numm_0.1-1_all.deb

   Usage
       At its simplest, numm provides three pairs of invertable functions that connect common media formats with numpy:

       Images represented as (height, width, color) numpy.uint8 arrays.

       o   image2np(path) -> np

       o   np2image(np, path)

       Sounds as (frames, channels) numpy.int16s

       o   sound2np(path) -> np

       o   np2sound(np, path)	      # XXX: must be .wav

       Videos as (frames, height, width, color) numpy.uint8s

       o   video2np(path) -> np

       o   np2video(np, path)	      # XXX: must be .mkv

       For  rapid-prototyping  of  interactive	numpy-based  audio-visual  experiments,  the  numm package has a real-time mode.  The numm package
       installs a program named numm-run, which launches (and reloads on modification) python scripts that may implement any subset of the follow-
       ing functions, which are asynchronously called as needed:

       o   video_in(a)			    # webcam

       o   video_out(a) 		    # mutate a in-place to set video

       o   audio_in(a)			    # mic

       o   audio_out(a) 		    # mutate a for audio output

       o   mouse_in(type, px, py, button)

       o   keyboard_in(type, key)

NAME

       update-python-modules - byte-compile python modules

SYNOPSIS

       update-python-modules [options] [package.public [...]]

DESCRIPTION

       The update-python-modules command is part of the python-support bundle.

       update-python-modules  is  responsible for the byte-compilation of python modules. When used in byte-compilation mode, it will byte-compile
       modules references in the files given on the command line. When used in	installation  mode,  it  will  byte-compile  them  once  for  each
       installed python version, and will make them available for all of them.

       At  each  invocation,  with  or without arguments, update-python-modules will check for installed python versions, and will build or remove
       modules according to new or removed versions since the last time it was run.

ARGUMENTS

       Arguments must be files or directories located in the /usr/share/python-support directory. Depending on their extension, they  are  treated
       differently.

       package.public
	      A file listing public modules to install for each version. These modules must lie in /usr/share/pyshared or /usr/lib/pyshared.

       package.private
	      A file listing private modules to byte-compile for one Python version.

       package/
	      A legacy directory hierarchy of public modules. The C extensions and portions that change with the Python version are to be found in
	      /usr/lib/python-support/pythonX.Y/package/.

       package.dirs
	      A legacy file listing directories where to find private modules.

OPTIONS

       -h, --help
	      Show summary of options.

       -v, --verbose
	      Detail all actions while they are performed.

       -b, --bytecompile
	      Only accept to work on private modules. When given this option, update-python-modules will fail if passed references to public  mod-
	      ules.

       -i, --install
	      Only  accept  to work on public modules. When given this option, update-python-modules will fail if passed references to public mod-
	      ules.

       -c, --clean
	      Clean modules instead of installing them.

       -a, --rebuild-all
	      Rebuild all private modules. This is necessary when the default python version was changed, for example.

       -f, --force-rebuild-all
	      Clean all modules (public and private), and rebuild them.

FILES

       /usr/lib/pymodules/pythonX.Y/
	      These directories contain the byte-compiled modules for version pythonX.Y.
