[Haskell-cafe] Text report tools?

Hi, I am looking for an easy way to generate text reports. For starters I need a very simple report that may contain: - Some headers - Lists of text strings where each string can include instances of basic Haskell types. Each string should be printed on a separate line (terminated with LF). Do I understand this right that for such simple reports (as above) Text.Printf is the main tool? As a next step, a simple report engine controlled by templates or DSL would help. Thanks!
