=head1 DESCRIPTION
C<ExtUtils::Mksymlists> produces files used by the linker under some OSs
-during the creation of shared libraries for synamic extensions. It is
+during the creation of shared libraries for dynamic extensions. It is
normally called from a MakeMaker-generated Makefile when the extension
is built. The linker option file is generated by calling the function
C<Mksymlists>, which is exported by default from C<ExtUtils::Mksymlists>.
It takes one argument, a list of key-value pairs, in which the following
keys are recognized:
+=over
+
=item NAME
This gives the name of the extension (I<e.g.> Tk::Canvas) for which
associative array, in which each key is the name of a package, and
each value is an a reference to an array of function names which
should be exported by the extension. For instance, one might say
-C<DL_FUNCS => { Homer::Iliad => [ qw(trojans greeks) ],
-Homer::Odyssey => [ qw(travellers family suitors) ] }>. The
+C<DL_FUNCS =E<gt> { Homer::Iliad =E<gt> [ qw(trojans greeks) ],
+Homer::Odyssey =E<gt> [ qw(travellers family suitors) ] }>. The
function names should be identical to those in the XSUB code;
C<Mksymlists> will alter the names written to the linker option
file to match the changes made by F<xsubpp>. In addition, if
name of the extension). If it is not specified, it is derived
from the NAME attribute. It is presently used only by OS2.
+=back
+
When calling C<Mksymlists>, one should always specify the NAME
attribute. In most cases, this is all that's necessary. In
the case of unusual extensions, however, the other attributes
