As in a general multi-purpose tool. It is a word that everybody understands, but I would like to know some alternatives.
Clarification: The term Swiss army knife is often used to express a multi-purpose, versatile tool outside the contexts of knives or armies.
- The Swiss army knife for writing books.
- Perl is the Swiss army knife among programming languages.
- Swiss army knife of codecs (Google's search entry completion).
I think that "multi-tool" or "one stop shop" are adequate alternative, maybe there are more???
