I run metapost a lot and am very pleased with it, especially the possibility to mix graphics and math symbols.
But sometimes I get fat a line in the rigth margin as a result from  mproof, for instance 
    >tex mproof fig.1 && dvips mproof.dvi -o mproof.ps

It seems it's because the lines I try to write becomes too long,  (I get an error message saying something about too long lines)
I guess it's because something in tex that does it.
How can I get around it?

Edit mproof.tex, adding \overfullrule=0pt near the top. TeX may still complain that the line is too long, but the rule it places to mark the overfull line will have width 0pt and be invisible. -- Dan Luecking Dept. of Mathematical Sciences luecking@uark.edu University of Arkansas http://comp.uark.edu/~luecking/ Fayetteville, AR 72101 From - Sun Oct 28 03:44:58 2001 Return-Path: Received: from coxeter.math.toronto.edu (coxeter.math.toronto.edu [128.100.68.3]) by nef.ens.fr (8.10.1/1.01.28121999) with ESMTP id f9S2inl37437 for ; Sun, 28 Oct 2001 03:44:49 +0100 (CET) Received: (from laurent@localhost) by coxeter.math.toronto.edu (8.11.0/8.11.0/UTMath 1.0) id f9S2ihM94458; Sat, 27 Oct 2001 22:44:43 -0400 Date: Sat, 27 Oct 2001 22:44:43 -0400 From: Larry Siebenmann Message-Id: <200110280244.f9S2ihM94458@coxeter.math.toronto.edu> To: Lars.Hellstrom@math.umu.se, beebe@math.utah.edu, lcs@math.toronto.edu, metafont@ens.fr X-Virus-Scanner: AMaVis 0.2.0-pre6 / Virus Scan X-Loop: metafont@nef.ens.fr X-Sequence: 492 Precedence: list Subject: [metafont] does MF draw NURBs ??
