    Early versions of this were based on Vim's Automake syntax highlighting
    file. This language definition is for Automake's Makefile.am files. It is
    based on the definition of Makefile, except it highlights Makefile variables
    which are significant to Automake, as well as Autoconf-style @variable@
    substitutions.
