gridset
Experimental grid-typesetting package — explicitly not recommended for production use by its author.
The package gridset originates from frequent questions in the Usenet group
de.comp.text.tex, on the TeX-D-L
mailing list, and in the former forum at
komascript.de. The result was a hastily assembled
package that, with the help of a few manually placed markers, enables grid
typesetting.
The package was, however, always intended only as an experimental first step. Production use was always — and still is — discouraged. Publishing it at all is now considered a mistake by the author. The only reason it has not been fully withdrawn is that, against all warnings, a few users have come to rely on it. Nonetheless, there is no support for this package whatsoever.
Anyone willing to take it over, bring it to actual release readiness, and maintain it in the future is welcome to get in touch about a maintainer takeover.
The project is hosted on GitHub. See the CTAN catalogue entry for more.
