# This script is designed to remove all non-API global symbols from an object
|
|
# file. The only global symbols that should be retained are those that belong
|
|
# to the official namespace. Unfortunately doing this is platform-specific, as
|
|
# the object file manipulation tools are not consistent across platforms.
|
|
#
|
|
# On platforms where this script does not know what to do, the object file
|
|
# will retain non-API global symbols, and this may have unpleasant side effects.
|
|
#
|
|
# Prefixes that belong to the official namespace are:
|
|
# ast_
|
|
# _ast_
|
|
# __ast_
|
|
# astman_
|
|
# pbx_
|
|
# resample_
