# A very simple script to list all entrypoints that are used by either a test
# program, or within the libraries. This relies on the output format of 'nm',
# and assumes that the libraries are configured with TRACE defined, and using
# these options:
# --disable-macros
# --enable-sp-funcs
# --enable-widec
# Static libraries are used, to provide some filtering based on internal usage
# of the different symbols.
# keep the sorting independent of locale:
