# The dist package (which contains metaconfig) is available via SVN:
# svn co https://svn.sourceforge.net/svnroot/dist/trunk/dist
#
+# Though this script was generated by metaconfig from metaunits, it is
+# OK to send patches against Configure itself. It's up to the Configure
+# pumpkin to backport the patch to the metaunits if it is accepted.
+# For more information on patching Configure, see pod/perlhack.pod
+#
+# The metaunits are also available from the public git repository:
+# http://perl5.git.perl.org/metaconfig.git/ or
+# $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
