=head1 DESCRIPTION
-I<h2xs> builds a Perl extension from any C header file. The extension will
-include functions which can be used to retrieve the value of any #define
-statement which was in the C header.
+I<h2xs> builds a Perl extension from C header files. The extension
+will include functions which can be used to retrieve the value of any
+#define statement which was in the C header files.
The I<module_name> will be used for the name of the extension. If
-module_name is not supplied then the name of the header file will be used,
-with the first character capitalized.
+module_name is not supplied then the name of the first header file
+will be used, with the first character capitalized.
If the extension might need extra libraries, they should be included
here. The extension Makefile.PL will take care of checking whether
