# A very simple script to list 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-widec
# Static libraries are used, to provide some filtering based on internal usage
# of the different symbols.

# keep the sorting independent of locale:
