Un mensaje de Javier de la Cueva acerca de las entidades de gestión despertó mi curiosidad sobre el tema. Tras pocos segundos llegué a la página del Ministerio de Cultura, donde existe una lista con las ocho entidades autorizadas en España:

• Artistas Intérpretes Sociedad de Gestión (AISGE)
• Asociación de Gestión de Derechos Intelectuales (AGEDI)
• Centro Español de Derechos Reprográficos (CEDRO)
• Derechos de Autor de Medios Audiovisuales (DAMA)
• Entidad de Gestión de Derechos de los Productores Audiovisuales (EGEDA)
• Sociedad de Artistas Intérpretes o Ejecutantes de España (AIE)
• Sociedad General de Autores y Editores (SGAE)
• Visual Entidad de Gestión de Artistas Plásticos (VEGAP)

Acabo de crear una cuenta en Twitter por si le encuentro alguna utilidad, y escribo esto básicamente para probar el “acortador” de Google en mi primer “tweet”.

Parece que a Google le ha dado por situar en primera posición mi página cuando alguien busca información sobre el comando depmod (al menos es así en el momento de escribir esto). Y dado que el porcentaje de rebote es del 100% para esta búsqueda, he decidido que sería una buena idea que los visitantes encuentren lo que están buscando a la primera.

Lo que viene a continuación es una reproducción casi literal de la página de manual del comando depmod que he obtenido de Ubuntu 9.10.

NAME
  depmod - program to generate modules.dep and map files.

SYNOPSIS
  depmod [ -b basedir ] [ -e ] [ -F System.map ] [ -n ] [ -v ]
    [ version ] [ -A ]
  depmod [ -e ] [ -FSystem.map ] [ -n ] [ -v ] [ version ]
    [ filename... ]

DESCRIPTION
  Linux kernel modules can provide services (called "symbols")
  for other modules to use (using EXPORT_SYMBOL in the code). If
  a second module uses this symbol, that second module clearly
  depends on the first module. These dependencies can get quite
  complex.

  depmod creates a list of module dependencies by reading each
  module under /lib/modules/version and determining what symbols
  it exports and what symbols it needs. By default, this list is
  written to modules.dep in the same directory. If filenames are
  given on the command line, only those modules are examined
  (which is rarely useful unless all modules are listed).

  If a version is provided, then that kernel version's module
  directory is used rather than the current kernel version (as
  returned by uname -r).

  depmod will also generate various map files in this directory
  for use by the hotplug infrastructure.

OPTIONS
  -a --all
    Probe all modules. This option is enabled by default if no
    file names are given in the command-line.

  -A --quick
    This option scans to see if any modules are newer than the
    modules.dep file before any work is done: if not, it silently
    exits rather than regenerating the files.

  -b basedir --basedir basedir
    If your modules are not currently in the (normal) directory
    /lib/modules/version, but in a staging area, you can specify
    a basedir which is prepended to the directory name. This
    basedir is stripped from the resulting modules.dep file, so
    it is ready to be moved into the normal location.

  -C --config file or directory
    This option overrides the default configuration file at
    /etc/depmod.conf (or the /etc/depmod.d/ directory if that
    is not found).

  -e --errsyms
    When combined with the -F option, this reports any symbols
    which a module needs which are not supplied by other modules
    or the kernel. Normally, any symbols not provided by modules
    are assumed to be provided by the kernel (which should be true
    in a perfect world).

  -F --filesyms System.map
    Supplied with the System.map produced when the kernel was
    built, this allows the -e option to report unresolved symbols.

  -h --help
    Print the help message and exit.

  -n --dry-run
    This sends the resulting modules.dep and the various map files
    to standard output rather than writing them into the module
    directory.

  -v --verbose
    In verbose mode, depmod will print (to stdout) all the symbols
    each module depends on and the module's file name which
    provides that symbol.

  -V --version
    Show version of program and exit. See below for caveats when
    run on older kernels.
