+" Vim indent file
+" Language: Perl
+" Author: Rafael Garcia-Suarez <rgarciasuarez@free.fr>
+" URL: http://rgarciasuarez.free.fr/vim/indent/perl.vim
+" Last Change: 2003 Apr 25
+
+" Suggestions and improvements by :
+" Aaron J. Sherman (use syntax for hints)
+" Artem Chuprina (play nice with folding)
+
+" TODO 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.
