Hi all! I've been working on my own troff macro package for the last couple of weeks, and I thought I'd share it with you here:
http://ankarstrom.se/~john/mu.html The package is called "mu". In summary: It is simple, flexible and small: u.tmac is only 417 lines. It has footnotes and tables of contents. It has no special registers or strings! For an example of an advanced document written with mu, see http://git.ankarstrom.se/mu/plain/README.pdf. I hope you find it interesting and perhaps even useful. Feel free to write any questions or feedback. Best regards John
