! \begin{notice}[warning]
!   While the \module{rexec} module is designed to perform as described
!   below, it does have a few known vulnerabilities which could be
!   exploited by carefully written code.  Thus it should not be relied
!   upon in situations requiring ``production ready'' security.  In such
!   situations, execution via sub-processes or very careful
!   ``cleansing'' of both code and data to be processed may be
!   necessary.  Alternatively, help in patching known \module{rexec}
!   vulnerabilities would be welcomed.
