\usage{
o_config_info(var = c("CC", "CC_VERSION", "FC"))
}
\arguments{
\item{var}{name of the configuration variable to retrieve.}
}
\description{
Retrieves configuration and installation information about 
the embedded instance of Octave currently used by \pkg{RcppOctave}.
}
\note{
In Octave 4.0.0., variables \code{CC_VERSION} and \code{CXX_VERSION} 
were renamed \code{GCC_VERSION} and \code{GXX_VERSION} respectively.
\code{o_config_info} supports both values, querying the right ones
depending on the linked Octave version.
