| libtool.sh runs the command passed to it using "xcrun libtool". | |
| It creates symbolic links for all input files with a content-hash appended | |
| to their original name (foo.o becomes foo_{md5sum}.o). This is to circumvent | |
| a bug in the original tool that arises when two input files have the same | |
| base name (even if they are in different directories). | |
| xcrun only runs on Darwin, so libtool.sh only runs on Darwin. | |
