+# module is already big enough, and I want to make this class a bit more
+# complex to simplify some common cases ("foo" module in "foo.c") and do
+# better error-checking ("foo.c" actually exists).

+class Extension:
+ """Just a collection of attributes that describes an extension
+ module and everything needed to build it (hopefully in a portable
+ way, but there are hooks that let you be as unportable as you need).
+
+ Instance attributes:
+ name : string
+ the full name of the extension, including any packages -- ie.
+ *not* a filename or pathname, but Python dotted name
+ sources : [string]
+ list of source filenames, relative to the distribution root
+ (where the setup script lives), in Unix form (slash-separated)
+ for portability. Source files may be C, C++, SWIG (.i),
+ platform-specific resource files, or whatever else is recognized
+ by the "build_ext" command as source for a Python extension.
+ include_dirs : [string]
+ list of directories to search for C/C++ header files (in Unix
+ form for portability)
+ define_macros : [(name : string, value : string|None)]
+ list of macros to define; each macro is defined using a 2-tuple,
+ where 'value' is either the string to define it to or None to
+ define it without a particular value (equivalent of "#define
+ FOO" in source or -DFOO on Unix C compiler command line)
+ undef_macros : [string]
+ list of macros to undefine explicitly
+ library_dirs : [string]
+ list of directories to search for C/C++ libraries at link time
+ libraries : [string]
+ list of library names (not filenames or paths) to link against
+ runtime_library_dirs : [string]
+ list of directories to search for C/C++ libraries at run time
+ (for shared extensions, this is when the extension is loaded)
+ extra_objects : [string]
+ list of extra files to link with (eg. object files not implied
+ by 'sources', static library that must be explicitly specified,
+ binary resource files, etc.)
+ extra_compile_args : [string]
+ any extra platform- and compiler-specific information to use
+ when compiling the source files in 'sources'. For platforms and
+ compilers where "command line" makes sense, this is typically a
+ list of command-line arguments, but for other platforms it could
+ be anything.
+ extra_link_args : [string]
+ any extra platform- and compiler-specific information to use
+ when linking object files together to create the extension (or
+ to create a new static Python interpreter). Similar
+ interpretation as for 'extra_compile_args'.
+ export_symbols : [string]
+ list of symbols to be exported from a shared extension. Not
+ used on all platforms, and not generally necessary for Python
+ extensions, which typically export exactly one symbol: "init" +
+ extension_name.
+ swig_opts : [string]
+ any extra options to pass to SWIG if a source file has the .i
+ extension.
+ depends : [string]
+ list of files that the extension depends on
+ language : string
+ extension language (i.e. "c", "c++", "objc"). Will be detected
+ from the source extensions if not provided.
