\arguments{
  \item{x}{ a vector of mode \code{character} }
}
\details{
  This a simple (and not particularly fast) function to compute the GC
  content of sequence. When speed is an issue, one should use the
  function in the package \code{matchprobes}. This function only exists
  to avoid dependency on this package.
}
\value{
  The GC content (\code{numeric})
}
