+
+The packages below implement functions for generating properly
+formatted commandlines for the compiler being used. Each package
+defines two primary functions 'format_linker_cmd()' &
+'format_compiler_cmd()' that accepts a list of named arguments (a
+hash) and returns a list of formatted options suitable for invoking the
+compiler. By default, if the compiler supports scripting of its
+operation then a script file is built containing the options while
+those options are removed from the commandline, and a reference to the
+script is pushed onto the commandline in their place. Scripting the
+compiler in this way helps to avoid the problems associated with long
+commandlines under some shells.

+=head1 NAME
+
+ExtUtils::CBuilder::Platform::Windows - Builder class for Windows platforms
+
+=head1 DESCRIPTION
+
+This module implements the Windows-specific parts of ExtUtils::CBuilder.
+Most of the Windows-specific stuff has to do with compiling and
+linking C code.  Currently we support the 3 compilers perl itself
+supports: MSVC, BCC, and GCC.
+
+This module inherits from C<ExtUtils::CBuilder::Base>, so any functionality
+not implemented here will be implemented there.  The interfaces are
+defined by the L<ExtUtils::CBuilder> documentation.
