# libtool.sh runs the command passed to it using "xcrunwrapper 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).

# using this script, move the symlinking behavior to this script.
