The build-aux Directory

File: bison++.in (build-aux/bin)

This is a wrapper around Bison, tailored to produce C++ parsers. Compared to bison, bison++ updates the output files only if changed. For a file such as location.hh, virtually included by the whole front-end, this is a big win.

Also, bison outputs '\file location.hh' in Doxygen documentation, which clashes with ast/location.hh. bison++ changes this into '\file parse/location.hh'.

File: flex++.in(build-aux/bin)

A wrapper around Flex, to simplify and improve the generation of C++ scanners.

File: tiger.el(build-aux)

This file provides an Emacs major mode for Tiger programs (*.tig). Read it to get installation instructions.

Files: tiger-ftdetect.vim and tiger-syntax.vim(build-aux)

Vim scripts to detect and enable syntax highlighting for Tiger files.
