Commit kovacicODE.texi with content as shown in maxima-discuss message "how to add texi file" 2014-04-02.
Modify kovacicODE.texi to conform to maxima/share/template-standalone.texi,
which quiets warnings and errors from makeinfo, and generates a .info file
which can be parsed by maxima/doc/info/build_index.pl.
With these changes, I find that the following commands:
$ makeinfo kovacicODE.texi
$ perl path/to/build_index.pl kovacicODE.texi > kovacicODE-index.lisp
yields an index which can be loaded into Maxima:
(%o1) load("kovacicODE-index.lisp");
and then ? kovacicODE finds and displays the description of the function
and ?? kovacicODE finds and displays the "Introduction to ..." and "Functions and
variables ..." sections.
