+# This script processes NSS .def files according to the rules defined in
+# a comment at the top of each one. The files are used to define the
+# exports from NSS shared libraries, with -DEFFILE on Windows, a linker
+# script on Linux, or with -exported_symbols_list on OS X.
+#
+# The NSS build system processes them using a series of sed replacements,
+# but the Mozilla build system is already running a Python script to generate
+# the file so it's simpler to just do the replacement in Python.
+#
+# One difference between the NSS build system and Mozilla's is that
+# Mozilla's supports building on Linux for Windows using MinGW. MinGW
+# expects all lines containing ;+ removed and all ;- tokens removed.
