dangerous code blocks. @code{:eval query} will require a query for every
execution of a code block regardless of the value of the
``query''. @code{:eval never} (or @code{:eval no}) will ensure that a code
block is never evaluated, this can be useful for protecting against the
evaluation of dangerous code blocks. @code{:eval query} will require a query
for every execution of a code block regardless of the value of the
@code{org-confirm-babel-evaluate} variable.
