We welcome bug reports and suggestions for any aspect of the Texinfo system: programs, documentation, installation, etc. Please email them to firstname.lastname@example.org. You can get the latest version of Texinfo via its home page, http://www.gnu.org/software/texinfo.
For bug reports, please include enough information for the maintainers to reproduce the problem. Generally speaking, that means:
When in doubt whether something is needed or not, include it. It’s better to include too much than to leave out something important.
It is critical to send an actual input file that reproduces the problem. What’s not critical is to “narrow down” the example to the smallest possible input—the actual input with which you discovered the bug will suffice. (Of course, if you do do experiments, the smaller the input file, the better.)
Patches are most welcome; if possible, please make them with ‘diff -c’ (see Comparing and Merging Files) and include ChangeLog entries (see Change Log in The GNU Emacs Manual), and follow the existing coding style.
