Changelog:
2010.09.06 - 0.7-beta1
- features: vsprintf, support for named placeholders
- enhancements: format cache, reduced global namespace pollution

2010.05.22 - 0.6:
- reverted to 0.4 and fixed the bug regarding the sign of the number 0
Note:
Thanks to Raphael Pigulla <raph (at] n3rd [dot) org> (http://www.n3rd.org/)
who warned me about a bug in 0.5, I discovered that the last update was
a regress. I appologize for that.

2010.05.09 - 0.5:
- bug fix: 0 is now preceeded with a + sign
- bug fix: the sign was not at the right position on padded results (Kamal Abdali)
- switched from GPL to BSD license

2007.10.21 - 0.4:
- unit test and patch (David Baird)

2007.09.17 - 0.3:
- bug fix: no longer throws exception on empty paramenters (Hans Pufal)

2007.09.11 - 0.2:
- feature: added argument swapping

2007.04.03 - 0.1:
- initial release
