Changelog of @hackage/multiarg 0.12.0.0

Release 0.2.0.0, April 2, 2012 Changes since release 0.1.0.0:

Henceforth all public releases will have only even numbers in their release numbers (e.g. 0.2.0.0, 0.2.0.2, etc.) If a release has any odd numbers in its version, it is a development release.
QuickCheck tests are removed. Eventually I will reimplement these in a separate library package.
Added Feed function to System.Console.MultiArg.Prim; this allows you to carry out stateful parses without using a user state. Sometimes this aids in composability--for instance, I use it when combining parsers from different parts of the same program.

Release 0.4.0.0, June 30, 2012 Changes since release 0.2.0.0:

Code written for version 0.2.* will not work at all with this version.
Removed dependency on text library. multiarg now only deals with plain Strings. The memory usage concerns that originally led me to use Texts were unfounded.
Dramatically simplified code for primitive parsers. No more custom error types, monad transformers, or user states. This sort of functionality is easily implemented in the parsers that you can build; baking it into the primitive parsers makes things needlessly complicated.
Reworked included combinators in Combinator module.

Release 0.6.0.0, September 28, 2012 Changes since release 0.4.0.0:

Release 0.8.0.0, January 8, 2013 Changes since release 0.6.0.0:

Added a multi-mode parser to SimpleParser
All modules (except SampleParser) are now re-exported from System.Console.MultiArg. Therefore one import will bring in all of MultiArg. However, this introduced a naming conflict, because SimpleParser and Prim both had functions named "parse". Therefore I renamed SimpleParser.parse to "simple".
Removed the combinator from Prim and replaced it with
. Removed from Combinator. The new behaves as one would
expect from Parsec.
Simplified errors. There is now just one type of error message, and that is a string. Reversed error messages when Prim.parse returns (this way they are in the order the user would expect.)
Client code written for 0.6.0.0 will probably break with this release, mostly because of changes to the export lists. Combinator no longer re-exports from other modules, because now the expectation is that if you want to import everything you just import System.Console.MultiArg. So fixing that is just a matter of changing imports in client code. Other breakage will be limited to error handling code.

Release 0.10.0.0, March 7, 2013 Changes since release 0.8.0.0:

Added the simpleWithHelp and modesWithHelp pre-built parsers to the SimpleParser module
Added the mHelp field to the Mode record to allow for the modesWithHelp pre-built parser
Changed the modes function in the SimpleParser module. The new function has a simpler type. It will however break old code.

Release 0.12.0.0, March 27, 2013 Changes since release 0.10.0.0:

Added value constructors to the Combinator module to allow for easier parsing of option arguments that can fail to parse
Added automatic "Enter -h for help" to simpleWithHelp and modesWithHelp functions in SimpleParser
