      7 # This script processes NSS .def files according to the rules defined in
      8 # a comment at the top of each one. The files are used to define the
      9 # exports from NSS shared libraries, with -DEFFILE on Windows, a linker
     10 # script on Linux, or with -exported_symbols_list on OS X.
     11 #
     12 # The NSS build system processes them using a series of sed replacements,
     13 # but the Mozilla build system is already running a Python script to generate
     14 # the file so it's simpler to just do the replacement in Python.
     15 #
     16 # One difference between the NSS build system and Mozilla's is that
     17 # Mozilla's supports building on Linux for Windows using MinGW. MinGW
     18 # expects all lines containing ;+ removed and all ;- tokens removed.
