We used to set PATH in emacs, but because babel executes "sh" via shell-command, the configuration of the main shell may supersedes ours. * doc/org/ltl2tgba.org, doc/org/ltl2tgta.org, doc/org/ltlcross.org, doc/org/ltlfilt.org, doc/org/randltl.org, doc/org/tools.org, doc/org/genltl.org: Move all local-file variable to... * doc/org/.dir-locals.el: ... here. And also set the PATH in org-babel-sh-command. * doc/org/init.el.in: Set the PATH in org-babel-sh-command.
