Hi Henning, Thanks for the many suggestions.

The primary features of Palindromes include:

You made me curious, whether there are palindromes in my texts. However, I have some difficulties getting sensible results from it. First I found a long palindrome, that was actually a code example for an array definition.
This was using the option -t I suppose.
So I wondered, whether this palindrome shadows nicer shorter palindromes in the same text.
Indeed it might. By using -ts you will get all text palindromes around every position in the string, but I guess you found this option (the description of which was not correct, as you noticed). But on a long text you get (probably too) many results.
How about an option for showing the n longest palindromes or palindromes with length larger than n?
This makes sense. I will add an option -n which takes a number n and outputs all palindromes of length at least n.
Then I found a palindrome in Functi[on sin is no]t defined How about restricting text palindromes to sequences that are bounded by space and punctuation?
This makes sense as well.
The Palindrome welcome message is a bit disturbing when running palindrome on a set of files.
I see. I'll remove it.
I also like to filter out HTML markup (with strip-html from tagchup package), before piping into palindrome. This however would require to run palindrome on standard input.
Again, this makes sense.
The options are '-x' for a single answer and '-xs' for multiple answers, but for '-ts' this logic does not hold. How about '-lt' or '-tl' ? I would like to have '-ts' to print all text palindromes (or actually, I would like to get all palindromes with at least 5 characters).
Corrected.
Documentation -------------
The API is documented using Haddock and available on the Palindromes package site.
It says, that the executable is FindingPalindromes, but actually it is palindromes, right?
Right.
Pretty much suggestions, I know. Don't get worried and thank you for the program!
You're welcome, thanks for the suggestions. I'll try to upload a new version of palindromes that includes your suggestions in the next couple of weeks. -- Johan
