Option that allows additional parameters

[kvchernyaev]

The existing option
AdditionalArgumentsSettings.AcceptAdditionalArguments = true
throws an exception UnknownArgumentException if a not defined parameter passed.
I need an option to allow unknown arguments.

Check out https://github.com/j-maly/CommandLineParser/wiki/Command-line-format
AcceptAdditionalArguments allows to verify parameters not starting with - or --, like the directories in this example:
Finder.exe -s 3 --distinct directory1 directory2 directory3

If you want to allow unkown arguments starting with - or --, this is not supported.

Can i do it myself and make pull request?
I want to allow (by option) parameters

1. obsoleted and excluded from source code
2. like -Dname=val so pairs (name,val) can be used as not strictly defined configuration

[j-maly]

Sounds interesting, sure, I am happy to accept pull requests

Maybe that should be done in

CommandLineParser/src/CommandLineArgumentsParser/CommandLineParser.cs

Line 595 in 40120ac

public Argument LookupArgument(string argName)

Such that LookupArgument() should return a new instance of an Argument derived type if no argument is found ?
