Merge all C# project source files into a single one.
From terminal:
$ git clone https://github.com/gsscoder/commandline CommandLine
$ cd CommandLine/src/CommandLine
$ mono MergeSource.exe -p CommandLine.csproj -o $HOME/YourNewProject/CompleteSourceOfCommandLine.csNow you can include CompleteSourceOfCommandLine.cs into your C# project instead of adding reference with NuGet.
