Lib for parsing command line parameters.

Influenced by getopt.

In your main method, just specify which option you support. Each option has a delegate that is called when the option is found, use it to set your local variables.

var opts = new GetOpt("Sample application that sorts input rows based on a delimeted field", 
	new[]
		{
			new CommandLineOption('s', "separator", "Field separator", 
				ParameterType.String, o => separator = (string)o),
			new CommandLineOption('v', "verbose", "Show more info about found files", 
				ParameterType.None, o => verbose = true),
			new CommandLineOption('n', "numeric", "sort numerically", 
				ParameterType.None, o => numeric = true),
			new CommandLineOption('f',"field","Which field to sort by. Default = 0", 
				ParameterType.Integer, o => field = (int)o),
			new CommandLineOption("file", ParameterType.String, o => file = (string)o, true),
		});

Then parse the command line options like this (preferably inside a try/catch since it throws exceptions on errors):

 opts.ParseOptions(args);

The lib has a built-in ShowUsage function that gives you this output if you call it (or call the program with the build-in "-h" option):

Sample application that sorts input rows based on a delimeted field
Usage: SampleApp -vnh -s <String> -f <Integer> [file]
Options:
 -s --separator <String> : Field separator
 -v --verbose            : Show more info about found files
 -n --numeric            : sort numerically
 -f --field <Integer>    : Which field to sort by. Default = 0
 -h --help               : This help

To create a stand-along exe (that doesn't require the Jokedst.GetOpt.dll) you can use ILMerge.exe from Microsoft.

The sample app in this repo creates a "combined.exe" file using a post-build build step.
