We welcome bug reports and suggestions for any aspect of the Texinfo system: programs, documentation, installation, etc. Please email them to email@example.com. 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.
Any problems with the Info reader in Emacs should be reported to the Emacs developers: see Bugs in The GNU Emacs Manual.
Patches are welcome; if possible, please make them with ‘diff -c’, ‘diff -u’ (see Comparing and Merging Files), or ‘git diff’ and include ChangeLog entries (see Change Log in GNU Coding Standards), and follow the existing coding style.
