I just thought it might be good to have an argument type that reads an argument until the end of line. That would be a special version of the u type, I think, but the normal user will not be able to specify it that way. Any comments? Based on my experience with Texinfo, my comment is that robust parsing of arguments delimited by end-of-line is essentially impossible. I fully agree with Joseph: I wouldn't go there. (Also I'm not sure about different line endings in *nix and Windows.) That isn't the problem. The engines have always unified the various platform-specific line endings to \endlinechar (otherwise TeX portability would be a nonstarter). The problem is distinguishing eol from space (gets converted very early in processing), handling the contexts of active eol vs. normal eol, doing all this inside other macros, etc. ... it's a steep and slippery slope. If you want to convert from TeX to OOo, my suggestion is to use an external program. An eol-delimited macro will hardly be a panacea for that job, as you yourself pointed out. k
