+#!/bin/sh
+# This script writes out all the exported symbols to a file
+# AIX needs this as sybmols are not exported by an
+# executable by default and we need to list
+# them specifically in order to export them
+# so that they can be used by native add-ons
+#
+# The raw symbol data is objtained by using nm on
+# the .a files which make up the node executable
+#
+# -Xany makes sure we get symbols on both
+# 32 bit and 64 bit as by default we'd only get those
+# for 32 bit
+#
+# -g selects only exported symbols
+#
+# -C, -B and -p ensure the output is in a format we
+# can easily parse and convert into the symbol we need
+#
+# -C suppresses the demangling of C++ names
+# -B gives us output in BSD format
+# -p displays the info in a standard portable output format
+#
+# We only include symbols if they are of the
+# following types and don't start with a dot.
+#
+# T - Global text symbol
+# D - Global data symbol
+# B - Gobal bss symbol.
+#
+# the final sort allows us to remove any duplicates
+#
+# We need to exclude gtest libraries as they are not
+# linked into the node executable
+#
