# script belongs to the public domain and cannot be copyrighted.
#
-# Note: this Configure script was generated automatically. Rather than
-# working with this copy of Configure, you may wish to get metaconfig.
-# The dist package (which contains metaconfig) is available via SVN:
-# svn co https://svn.code.sf.net/p/dist/code/trunk/dist
+# Note: this Configure script was generated automatically by the tool
+# called "metaconfig". Rather than working with this copy of Configure,
+# you should use metaconfig. Perl uses a modified version of this
+# tool, and this, together with the metaconfig units, are available
+# in the git repository:
+# $ git clone https://github.com/Perl/metaconfig metaconfig
+# The original dist package (including metaconfig) is available on github:
+# $ git clone https://github.com/rmanfredi/dist.git dist-git
#
# 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
-#
-# See Porting/pumpkin.pod for more information on metaconfig.
-#
+# OK to send patches against Configure itself (but not to commit them

+# the Configure maintainers to backport the patch to the metaunits if it
+# is accepted. Exceptions to this rule, and more information, is in
+# Porting/pumpkin.pod.
