A very simple Library using F#'s record types as command-line argument definition.
An example can be found in FSharp.CommandLine.Parser.Tests. The library currently only supports very basic features and I will extend it when needed. Please feel free to contribute.
I'm planning to use a GetOpt implementation underneath to ensure posix comliance.
FSharp.CLI can also be referenced via NuGet: https://www.nuget.org/packages/FSharp.CommandLine.Parser
