+# Fake "ar" to build the Python shared library on BeOS. This "ar"
+# manipulates a .ar-libname file listing all the objects and regenerates
+# the shared lib every time it's called. This is probably only suitable
+# for things that get built like Python, and you'll probably have to make
+# some small modifications here and there.
+#
+# This stupid hackery is necessary due to the brain-damaged __declspec()
+# semantics on x86; on PowerPC, we could just build a static library
+# and turn that into a shared library using an exports list. On x86, you'd
+# need to use a fake table of pointers to every symbol you wanted to
+# export, otherwise you'd end up with an empty shared lib. This is
+# progress?
+#
+# Called via:
+#
+# ar-fake cr lib-name objects
+# ar-fake d lib-name objects
+#
+# This fake "ar" DOES NOT support any other POSIX "ar" commands! DO NOT
+# expect it to behave very intelligently, it's designed to build Python,
+# not any old shared lib.
