12.8. Adding Descriptions to Files
Problem
You want to put a brief description of files in the listing.
Solution
Use the AddDescription directive to add a description to certain files or groups of files:
AddDescription "GIF image" .gif
Discussion
You may set a description for a particular file, or for any file that matches a particular pattern. The first argument to AddDescription is the description that you want to use, and the second is a substring that will be compared to file names. Any file that matches the pattern will have the description used for it.
By default, you have 23 characters available for this description. That space can be altered explicitly by setting IndexOptions DescriptionWidth, or by suppressing one of the other columns.
You should ensure that the description isn’t too long, or it will be truncated when it reaches the width limit. This can be annoying when the description is truncated and therefore unreadable. Also, because you’re permitted to use HTML in the description, it’s possible that the HTML could be truncated, leaving unclosed HTML tags.
