\subsection{Using Packages Without a Package}
\subsection{Using Packages Outside a Package}
\label{sec:meta-package}
In principle, packages can be used only inside another package
by declaring dependencies.
Thus, if you develop a Curry application which is not a package
but you want to use some package, you have to put
a package specification file into the source directory of
your application where you define the required packages.
As a shortcut for this, you can use the CPM command
\code{cypm add --dependency} (short: \code{cypm add -d})
to install the package specification file.
by declaring dependencies in the package specification file
\code{package.json}.
If you invoke \code{cypm} in a directory which contains
no package specification file, CPM searches for such a file
from the current directory to the parent directories (up to the
root of the file system).
Thus, if you are outside a package, such a file is not available.
In order to support the use other packages outside package,
CPM provides a meta-package which is usually stored in your home directory
at \code{\char126/.cpm/$Curry system$-homepackage}.\footnote{%
Use \code{cypm config} and look at \code{HOME_PACKAGE_PATH}
to see the current location of this meta-package.}
This meta-package is used when your are not inside another package.
Hence, if you write some Curry program which is not a package
but you want to use some package \code{P}, you have to add a dependency
to \code{P} to this meta-package.
CPM does this automatically for you with the CPM command
\code{cypm add --dependency} (short: \code{cypm add -d}).
For instance, to use the libraries of the JSON package
in your application, one can use the following commands:
%
\begin{lstlisting}
> cypm add -d json # generate package specification with 'json' dependency
> cypm add -d json # add 'json' dependency to meta-package
> cypm install # download and install all dependencies
> cypm curry # start Curry system with JSON libraries in load path

\code{cypm link} takes a directory containing a copy of one of the current
