+# Strip symbols inplace from the libraries in a zip archive.
+#
+# Stripping symbols is beneficial (reduction of 30% of the final package, >
+# %90% of the installed libraries. However just running `auditwheel repair
+# --strip` breaks some of the libraries included from the system, which fail at
+# import with errors such as "ELF load command address/offset not properly
+# aligned".
+#
+# System libraries are already pretty stripped. Ours go around 24Mb -> 1.5Mb...
+#
+# This script is designed to run on a wheel archive before auditwheel.
