# called "metaconfig". Rather than working with this copy of Configure,
# you may wish to get metaconfig. Perl uses a modified version of this
# tool, available in the "dist" folder in the checkout of the git repo
-# $ git clone git://perl5.git.perl.org/metaconfig.git metaconfig
+# $ git clone https://github.com/perl5-metaconfig/metaconfig metaconfig
# The original dist package (including metaconfig) is available via SVN:
-# $ svn co https://svn.code.sf.net/p/dist/code/trunk/dist
+# $ 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
+# The metaunits are also available from the public github repository:
+# https://github.com/perl5-metaconfig/metaconfig/tree/master/U
#
# See Porting/pumpkin.pod for more information on metaconfig.
