I have been scrutinising the Texinfo files for the book "Free Software Free Society" where he defines some macros in texinfo.tex
In the code file not-ipr.texi there is the command @chapter Did You Say ``Intellectual Property''?@entrybreak{}It's@tie{}a@tie{}Seductive@tie{}Mirage I do not think that @entrybreak{} is a standard texinfo command when checking the manual. In the file texinfo.tex I have found defined \def\entrybreak{\hfil\break}% I want to do a similar thing in one of my documents that uses @part because the part title is bit long and I would like to break it along multiple lines. Because I keep to 72 columns in the code, I want to split the long part titles, but have noticed that texinfo takes only the entry on the same line as @part. @alias ebr = entrybreak @set ta @ebr{}New Ideas in Seismic @set tb @ebr{}Observatory Practice @part PART I @*@*@* @value{ta}@*@value{tb} @part PART I @*@*@* @value{ta}@*@value{tb}
