\details{

  \code{NetAffxResource} creates a \code{\linkS4class{NetAffxResource}} object that
  manages a data base of NetAffx resources. The data base is located on
  the user file system as indicated by the \code{directory} arugment. It
  is populated when the user requests specific files.

  Users should provide a \code{directory} argument, so that the data
  base can be reused across sessions. This means that large files are
  only downloaded once.

  Additional details are provided in the vignette accompanying this
  package.
