I am extremely tired right now and don't have time to read through verbose drupal 7 documentation. Can someone just show me a quick Hello World example that will do the following in drupal 7?
I have a template file
/sites/all/themes/mytheme/page.tpl.php and in it I have
<?php echo "Hello World"; ?>
When a person comes to the page in English, it should show "Hello world". When the person comes to the page in French, it should show "Bonjour tout le monde". How do I augment the command echo "Hello World" to do such a thing? If language files are needed, show me how to structure them.
