+## @deftypefn {Command} pkg @var{command} @var{pkg_name}
+## @deftypefnx {Command} pkg @var{command} @var{option} @var{pkg_name}
+## This command interacts with the package manager. Different actions will
+## be taken depending on the value of @var{command}.
+##
+## @table @samp
+## @item install
+## Install named packages. For example,
+## @example
+## pkg install image-1.0.0.tar.gz
+## @end example
+## @noindent
+## installs the package found in the file @code{image-1.0.0.tar.gz}.
+##
+## The @var{option} variable can contain options that affect the manner
+## in which a package is installed. These options can be one or more of
+##
+## @table @code
+## @item -nodeps
+## The package manager will disable the dependency checking. That way it
+## is possible to install a package even if it depends on another package
+## that's not installed on the system. @strong{Use this option with care.}
+##
+## @item -noauto
+## The package manager will not automatically load the installed package
+## when starting Octave, even if the package requests that it is.
+##
+## @item -auto
+## The package manager will automatically load the installed package when
+## starting Octave, even if the package requests that it isn't.
+##
+## @item -local
+## A local installation is forced, even if the user has system privileges.
+##
+## @item -global
+## A global installation is forced, even if the user doesn't normally have
+## system privileges
+##
+## @item -verbose
+## The package manager will print the output of all of the commands that are
+## performed.
+## @end table
+##
+## @item uninstall
+## Uninstall named packages. For example,
+## @example
+## pkg uninstall image
+## @end example
+## @noindent
+## removes the @code{image} package from the system. If another installed
+## package depends on the @code{image} package an error will be issued.
+## The package can be uninstalled anyway by using the @code{-nodeps} option.
+## @item load
+## Add named packages to the path. After loading a package it is
+## possible to use the functions provided by the package. For example,
+## @example
+## pkg load image
+## @end example
+## @noindent
+## adds the @code{image} package to the path. It is possible to load all
+## installed packages at once with the command
+## @example
+## pkg load all
+## @end example
+## @item unload
+## Removes named packages from the path. After unloading a package it is
+## no longer possible to use the functions provided by the package.
+## This command behaves like the @code{load} command.
+## @item list
+## Show a list of the currently installed packages. By requesting one or two
+## output argument it is possible to get a list of the currently installed
+## packages. For example,
+## @example
+## installed_packages = pkg list;
+## @end example
+## @noindent
+## returns a cell array containing a structure for each installed package.
+## The command
+## @example
+## [@var{user_packages}, @var{system_packages}] = pkg list
+## @end example
+## @noindent
+## splits the list of installed packages into those who are installed by
+## the current user, and those installed by the system administrator.
+## @item describe
+## Show a short description of the named installed packages, with the option
+## '-verbose' also list functions provided by the package, e.g.:
+## @example
+## pkg describe -verbose all
+## @end example
+## @noindent
+## will describe all installed packages and the functions they provide.
+## If one output is requested a cell of structure containing the
+## description and list of functions of each package is returned as
+## output rather than printed on screen:
+## @example
+## desc = pkg ("describe", "secs1d", "image")
+## @end example
+## @noindent
+## If any of the requested packages is not installed, pkg returns an
+## error, unless a second output is requested:
+## @example
+## [ desc, flag] = pkg ("describe", "secs1d", "image")
+## @end example
+## @noindent
+## @var{flag} will take one of the values "Not installed", "Loaded" or
+## "Not loaded" for each of the named packages.
+## @item prefix
+## Set the installation prefix directory. For example,
+## @example
+## pkg prefix ~/my_octave_packages
+## @end example
+## @noindent
+## sets the installation prefix to @code{~/my_octave_packages}.
+## Packages will be installed in this directory.
+##
+## It is possible to get the current installation prefix by requesting an
+## output argument. For example,
+## @example
+## p = pkg prefix
+## @end example
+##
+## The location in which to install the architecture dependent files can be
+## independent specified with an addition argument. For example
+##
+## @example
+## pkg prefix ~/my_octave_packages ~/my_octave_packages_for_my_pc
+## @end example
+## @item local_list
+## Set the file in which to look for information on the locally
+## installed packages. Locally installed packages are those that are
+## typically available only to the current user. For example
+## @example
+## pkg local_list ~/.octave_packages
+## @end example
+## It is possible to get the current value of local_list with the following
+## @example
+## pkg local_list
+## @end example
+## @item global_list
+## Set the file in which to look for, for information on the globally
+## installed packages. Globally installed packages are those that are
+## typically available to all users. For example
+## @example
+## pkg global_list /usr/share/octave/octave_packages
+## @end example
+## It is possible to get the current value of global_list with the following
+## @example
+## pkg global_list
+## @end example
+## @item rebuild
+## Rebuilds the package database from the installed directories. This can
+## be used in cases where for some reason the package database is corrupted.
+## It can also take the @code{-auto} and @code{-noauto} options to allow the
+## autolaoding state of a package to be changed. For example
+##
+## @example
+## pkg rebuild -noauto image
+## @end example
+##
+## will remove the autoloading status of the image package.
+## @item build
+## Builds a binary form of a package or packages. The binary file produced
+## will itself be an Octave package that can be installed normally with
+## @code{pkg}. The form of the command to build a binary package is
+##
+## @example
+## pkg build builddir image-1.0.0.tar.gz @dots{}
+## @end example
+##
+## @noindent
+## where @code{buiddir} is the name of a directory where the temporary
+## installation will be produced and the binary packages will be found.
+## The options @code{-verbose} and @code{-nodeps} are respected, while
+## the other options are ignored.
+## @end table
