Is there a good simple software to convert ebooks in txt format?

I downloaded an ebook to my linux netbook. It is in a txt fomat and is unpleasant to read. I opened it in openoffice word and re-formatted it made it easier to read. I was wondering though if there was a free linux based software out there that would make reading txt ebooks more pleasant.

I found this link on fluther to a great free ebook website.
