https://en.wikipedia.org/wiki/LIBPATH had gotten redirected to https://en.wikipedia.org/wiki/CONFIG.SYS#LIBPATH, but LIBPATH is a meaningful environment variable on AIX as well. (There it means basically the same as https://en.wikipedia.org/wiki/LD_LIBRARY_PATH.) So I wanted to create a disambiguation article for LIBPATH instead of the “redirect thing“. That article helped me doing so.
