+
+The Exporter module will convert an attempt to import a number from a
+module into a call to $module_name->require_version($value). This can
+be used to validate that the version of the module being used is
+greater than or equal to the required version.
+
+The Exporter module supplies a default require_version method which
+checks the value of $VERSION in the exporting module.

+=head v4.16 June 18, 1995, by Tim Bunce
+
+Split test: target into test_static: and test_dynamic: with automatic
+selection based on LINKTYPE. The test_static: target automatically
+builds a local ./perl binary containing the extension and executes the
+tests using that binary. This fixes problems that users were having
+dealing with building and testing static extensions. It also simplifies
+the process down to the standard: make + make test.
+
+MakeMaker no longer incorrectly considers a perlmain.c file to be part
+of an extensions source files. The map_clean target is now invoked by
+clean not realclean and now deletes MAP_TARGET but does not delete
+Makefile (since that's done properly elsewhere).
+
+Since the staticmake section defines macros that the test target now
+needs the test section is written into the makefile after the
+staticmake section. The postamble section has been made last again, as
+it should be.

=head1 SYNOPSIS
-B<xsubpp> [B<-C++>] [B<-except>] [B<-typemap typemap>] file.xs
+B<xsubpp> [B<-C++>] [B<-except>] [B<-typemap typemap>]... file.xs
=head1 DESCRIPTION
to identify the exact line in the C<.xs> file where the fault occurs.
This can be achieved in the majority of cases.
+=head2 1.8
+
+Changes by Hallvard B Furuseth <h.b.furuseth@usit.uio.no>, 6 June 1995.
+
+Accept backslash-newline as in C. Allow preprocessor directives
+anywhere. Ignore whitespace in front of comments and on blank lines.
+
+=head2 1.9
+
+Changes by Paul Marquess <pmarquess@bfsec.bt.co.uk>, 21 June 1995.
+
+=over 5
+
+=item 1.
+
+Changed duplicate function error to a warning.
+
+=item 2.
+
+Changed the comment placed at the top of the C<.c> file to be more like
+the comment used by MakeMaker.
+
+=item 3.
+
+When parsing the type for an XSUB parameter I<xsubpp> can now accept
+definitions like this:
+
+ char *fred
+
+i.e. the '*' is recognised as part of the type, rather than the first
+character of the variable.
+
+=item 4.
+
+Fixed a problem with command line parsing - I<xsubpp> was not properly
+detecting the case where there was no filename present on the command
+line.

+=head1 NAME
+
+lib - manipulate @INC at compile time
+
+=head1 SYNOPSIS
+
+ use lib LIST;
+
+ no lib LIST;
+
+=head1 DESCRIPTION
+
+This is a small simple module which simplifies the manipulation of @INC
+at compile time.
+
+It is typically used to add extra directories to perl's search path so
+that later C<use> or C<require> statements will find modules which are
+not located on perl's default search path.
+
+
+=head2 ADDING DIRECTORIES TO @INC
+
+The parameters to C<use lib> are added to the start of the perl search
+path. Saying
+
+ use lib LIST;
+
+is the same as saying
+
+ BEGIN { unshift(@INC, LIST) }
+
+
+=head2 DELETING DIRECTORIES FROM @INC
+
+You should normally only add directories to @INC. If you need to
+delete directories from @INC take care to only delete those which you
+added yourself or which you are certain are not needed by other modules
+in your script. Other modules may have added directories which they
+need for correct operation.
+
+By default the C<no lib> statement deletes the I<first> instance of
+each named directory from @INC. To delete multiple instances of the
+same name from @INC you can specify the name multiple times.
+
+To delete I<all> instances of I<all> the specified names from @INC you can
+specify ':ALL' as the first parameter of C<no lib>. For example:
+
+ no lib qw(:ALL .);
+
+
+=head2 RESTORING ORIGINAL @INC
+
+When the lib module is first loaded it records the current value of @INC
+in an array C<@lib::ORIG_INC>. To restore @INC to that value you
+can say either
+
+ @INC = @lib::ORIG_INC;
+
+or
+
+ no lib @INC;
+ use lib @lib::ORIG_INC;
+
+=head1 SEE ALSO
+
+AddINC - optional module which deals with paths relative to the source file.
