 description: """
-This package provides the following Coq modules:
-iris.prelude, iris.algebra, iris.si_logic, iris.bi, iris.proofmode, iris.base_logic, iris.program_logic.
+Iris is a framework for reasoning about the safety of concurrent programs using
+concurrent separation logic. It can be used to develop a program logic, for
+defining logical relations, and for reasoning about type systems, among other
+applications. This package includes the base logic, Iris Proof Mode (IPM) /
+MoSeL, and a general language-independent program logic; see coq-iris-heap-lang
+for an instantiation of the program logic to a particular programming language.
