Q 0.5 What should I do with the try.sh and try.alt.sh scripts?

+If your submission has more than one use, or if you have interesting ways to
+invoke your program, perhaps using other commonly installed tools (or tools
+included in your submission), it can be helpful to include a try.sh script.
+A template try.sh can be used as a
+starting point, or you can look at some of the others in the website, to get
+some ideas.
+It is not detrimental to your chances of winning if you do not include one as
+not all submissions can make use of them. Nevertheless, it is helpful to include
+ways to use your program, and if you have creative ways this can be a bonus. It
+does not mean that a program that cannot be used with other programs is less
+interesting or less likely to win, but we do enjoy interesting and creative uses
+of submissions.
+If you have alternate code that you are including, then you can use the
+try.alt.sh template instead.
