The current version is buggy and not usable for any serious project. It uses GET instead of POST to talk to the Amazon API. As a result:
1) Any message with a special char such as '&' will fail (special chars are not escaped)
2) Any long message will fail due to the limitations in URL lengths.
I am not sure that the module is maintained (a bug has been open for two years with no apparent reaction).
I think that the previous (and unique) review is misleading. I use this module and never noticed anything wrong. I find it very useful and perfectly functional.
The comments below are rather negative, but they apply to 0.45. Since a new maintainer is in charge, and we are at 0.47, I wonder what the situation is now. Have the major bugs been fixed? Some feedback from other or the author would be great before we start installing and using. Thanks!
Excellent module, although I use it through Getopt::Long::Descriptive, which makes a very useful complement for building applications.
