Since `slibtool` is entirely + independent of the above wrappers with respect to its own functionality, + and given its announced goal to remain compatible with the script-based + libtool as much as possible, `slibtool`'s behavior is to always produce + `.la wrappers` on the one hand, yet fully ignore their content on the + other. + + Despite their internal nature, installed .la wrappers are often [ab]used + in strange and mysterious ways by distro-related tools other than libtool + itself. For the sake of distributions that depend on the aforementioned + wrappers, slibtool comes with three special symlinks named `clibtool`, + `clibtool-shared`, and `clibtool-static`, respectively. The `'c'` in + `clibtool` stands for `compatible`, and accordingly indicates an end-user's + preference towards perfect emulation of legacy behavior. + - `-rpath` argument values are passed to the compiler and linker as needed only; `-rpath` is often [mis]used by libtool to add redundant paths to a program's linker search path.
