+- As of openssl 3.1.3, the devel package installs at least 5200
+  manpage files and is the owner of the most files in the man3
+  directory (in second place after lapack-man); move these manpages
+  off to the -doc subpackage to reduce the walltime to install just
+  openssl-3-devel (because there is also an invocation of mandb
+  that runs at some point).
