		Usage: ${BASH_SOURCE[0]##*/} [OPTIONS]

		Searches for a locally built package corresponding to the PKGBUILD, and
		downloads the last version of that package from the Pacman repositories.
		It then compares the list of .so files provided by each version of the
		package and outputs if there are soname differences for the new package.
		A directory is also created using mktemp with files containing a file
		list for both packages and a library list for both packages.

		OPTIONS
		    -r, --rmdir          Remove the temporary directory
		    -w, --warn           Print a warning in case of differences
		    -M, --makepkg-config Set an alternate makepkg configuration file
		    -h, --help           Show this help text
