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
