-"""
-This tool supports the export_symbols_regex to export the symbols in a shared library.
-by default, all symbols are exported by gcc, and nothing by msvc.
-to use the tool, do something like:
-
-def build(ctx):
-	ctx(features='c cshlib syms', source='a.c b.c', export_symbols_regex='mylib_.*', target='testlib')
-
-only the symbols starting with 'mylib_' will be exported.
