What does ".tab" mean?

[Gabriel Czernikier]

Also, if the version of Bison you have allows it, with the directives:
%output "file"
and
%file-prefix "prefix"

For how to use this, see Bison Manual for version 3.0.4, section 3.7.12
"Bison Declaration Summary", installed in your system with Bison, and
available in the website.
