+ (description
+ "This package provides support for the @code{foreach} looping construct.
+@code{foreach} is an idiom that allows for iterating over elements in a
+collection, without the use of an explicit loop counter. This package in
+particular is intended to be used for its return value, rather than for its
+side effects. In that sense, it is similar to the standard @code{lapply}
+function, but doesn't require the evaluation of a function. Using
+@code{foreach} without side effects also facilitates executing the loop in
+parallel.")
