Trollop version 1.7.1 has been released!

- [http://trollop.rubyforge.org](http://trollop.rubyforge.org)

## DESCRIPTION

Trollop is YAFCLAP — yet another fine commandline argument processor  
for Ruby. Trollop is designed to provide the maximal amount of GNU-style  
argument processing in the minimum number of lines of code (for you, the  
programmer).

- Simple usage.
- Sensible defaults. No tweaking necessary, much tweaking possible.
- Support for long options, short options, short option bundling,  
and automatic type validation and conversion.
- Automatic help message generation, wrapped to current screen width.
- Lots of unit tests.

Just documentation changes. A couple things were updated, and the  
synopsis is now on the front page of the rdoc, by popular demand.

> BTW, I LOVE trollop and use it exclusively.

Thanks!
