cat <<- _EOF_
Usage: pkg-list-linked-libraries [-s] PACKAGE [LIBNAME|SYMBOL]
Check a package to see what libraries or symbols it links against.
Alternatively check against a specific library.
If PACKAGE is not an existing file, pacman will resolve it
as a package name and attempt to download it to the cache.
This respects repo/pkgname syntax.
OPTIONS
-s, --symbols Show symbols instead of libraries
-h, --help Show this help text
