\title{Check package dependencies}
\usage{
check_sen2r_deps()
}
\value{
NULL (the function is called for its side effects)
}
\description{
The function allows to graphically check that all the
optional runtime dependencies are installed.
}
\details{
This package needs some external dependencies in order to run
specific actions:
\itemize{
\item Sen2Cor for atmospheric correction;
\item GDAL for cloud mask smoothing and buffering;
\item aria2 to download SAFE images with an alternative downloader.
}

This function opens a GUI which allows to check that these dependencies
are installed. This check is highly suggested before using the library for
the fist time, in order to avoid errors.
