Using Macros

[Christopher Dimech]

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}
