[Palindromes] is a package for finding palindromes in files.



The primary features of [Palindromes] include:

* Linear-time algorithm for finding exact palindromes
* Linear-time algorithm for finding text palindromes,
ignoring spaces, case of characters, and punctuation
* Linear-time algorithm for finding word palindromes,
text palindromes surrounded by (if at all) non-letters.
* Linear-time algorithm for finding palindromes in DNA.
* Quadratic-time algorithm for finding approximate
palindromes, in which a limited number of symbols
may be substituted by other symbols
* Quadratic-time algorithm for finding palindromes with
gaps in the center.


[Palindromes] has the following requirements:

* [GHC] version 6.8.1 or later - It has been tested with version 7.4.1.
* [Cabal] library version 1.2.1 or later - It has been tested with version


Download & Installation

*If you have [cabal-install]*, you should use that to install the package,
because it will handle everything for you.

cabal install palindromes

*If you don't have cabal-install*, you must download the [Palindromes package]
from HackageDB and install it manually. Get the `tar.gz` file and decompress it.

Once downloaded, use the following commands for configuring, building, and
installing the library.

runghc Setup.lhs configure
runghc Setup.lhs build
runghc Setup.lhs install
