This should go elsewhere, e.g. lib/init. AIUI, the tools directory is
meant for things which aren't installed, e.g. tools for building or
maintaining GRASS rather than for using it.

BTW, we shouldn't need tools/getModtime any more; man/Makefile has
been fixed to use make's built in functionality instead.

Tcl doesn't have "global" variables like most languages. It has
"top-level" variables, but these aren't normally visible within
procedures. You need to use "global" to make it visible, i.e.:

	proc term {cmd args} {
	    global env
	    eval exec -- xterm -e $env(GISBASE)/etc/grass-run.sh $cmd $args &
	}
