The idea is that while every "config" command is different, at least they're all named the same, and users always see "config" in the list of standard commands. Also, this is a good place to put common configure-like tasks: "try to compile this C code", or "figure out where this header file lives". s $Id$i����N( t Command( t DistutilsExecError( t customize_compiler( t logs .ct cs .cxxs c++t configc B s. e Z d Z d, d- d. d/ d0 d1 d2 d3 d4 g Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d � Z d+ d+ d+ d! d" � Z d+ d+ d+ d! d# � Z d+ d+ d! d$ � Z d+ d+ d+ d+ d! d% � Z d+ d+ d+ d+ d! d& � Z d+ d+ d+ d+ d' d' d( � Z d+ d+ d+ g d) � Z d+ d+ d! d* � Z RS(5 s prepare to builds compiler=s specify the compiler types cc=s specify the compiler executables include-dirs=t Is. list of directories to search for header filess define=t Ds C preprocessor macros to defines undef=t Us!

If everything succeeds, returns true; otherwise returns false. The constructed source file starts out by including the header files listed in 'headers'. If 'decl' is true, it then declares 'func' (as "int func()"); you probably shouldn't supply 'headers' and set 'decl' true in the same call, or you might get errors about a conflicting declarations for 'func'. Finally, the constructed 'main()' function either references 'func' or (if 'call' is true) calls it.
