extensions ASAP).s5 $Id: build_ext.py 37828 2004-11-10 22:23:15Z loewis $N( t *( s Command( s customize_compilers get_python_version( s newer_group( s Extension( s logs3 ^[a-zA-Z_][a-zA-Z_0-9]*(\.[a-zA-Z_][a-zA-Z_0-9]*)*$c C s d k l } | d S( N( s show_compilers( t distutils.ccompilert show_compilers( R ( ( t1 /usr/lib/python2.4/distutils/command/build_ext.pyR s
