// really is executable (i.e., has main()). On the other hand, on
// some systems, this may be required in order for the dynamic
// linker to be able to load the library. So, by default, we will
// keep it executable, especially seeing that this is also the
// behavior of autotools. At the same time, it is easy to override
// this, for example:
//
// config.install.lib.mode=644
//
// And a library that wants to override any such overrides (e.g.,
// because it does have main()) can do:
//
// libso{foo}: install.mode=755
//
// Everyone is happy then?
//
install::path<libso> (b, "lib"); // Install into install.lib.
install::path<liba> (b, "lib"); // Install into install.lib.
