+" Vim indent file
+" Language:      Perl 6
+" Maintainer:    vim-perl <vim-perl@googlegroups.com>
+" Homepage:      http://github.com/vim-perl/vim-perl
+" Bugs/requests: http://github.com/vim-perl/vim-perl/issues
+" Last Change:   2017 Jun 13
+" Contributors:  Andy Lester <andy@petdance.com>
+"                Hinrik Örn Sigurðsson <hinrik.sig@gmail.com>
+"
+" Adapted from indent/perl.vim by Rafael Garcia-Suarez <rgarciasuarez@free.fr>
+
+" Suggestions and improvements by :
+"   Aaron J. Sherman (use syntax for hints)
+"   Artem Chuprina (play nice with folding)
+" TODO:
+" This file still relies on stuff from the Perl 5 syntax file, which Perl 6
+" does not use.
+"
+" Things that are not or not properly indented (yet) :
+" - Continued statements
+"     print "foo",
+"       "bar";
+"     print "foo"
+"       if bar();
+" - Multiline regular expressions (m//x)
+" (The following probably needs modifying the perl syntax file)
+" - qw() lists
+" - Heredocs with terminators that don't match \I\i*
+
+" Only load this indent file when no other was loaded.
