I have a function below that I (partially) wrote to handle a
particular situation.

I'm working with horse records in text files. I want to list all the
files with horse information in them, then a dash "-", then, a brief
description of the horse (taken from a separate text file). If that
description isn't in the text file, it leaves a blank line (so I know
to add it). The lines of extra information, as listed in separate
file, do not have to be in any order.

This all works: http://snowyriver.zzl.org/race_cards/index.php

I find that that scandir() also scans for subdirectories. I _only_
want to scan for .txt files. Scandir is good for me to use because it
alphabetizes the files without any additional work.

I would appreciate any help that could be offered as far as ways to
adjust my $files array so it's only made up of .txt files.

Thank you for reading this post!
