Is there a .NET port of the SED stream editor? Ideally it would be open source, but at this stage I'm not ruling anything out.
I have googled for this already without any obvious hits, so the secondary question here is: How hard would it be to create one?
I assume the sources for SED are in C. If the answer to my primary question is No, I would appreciate pointers/strategies for porting such a project to C#.
