As far as I remember ${FG_HOME} predates ${HOME}/.fgfs/ by approx. the
half of FlightGear's lifetime.  According to my understanding, from the
information I retrieved for writing parts of The Manual (_before_
${HOME}/.fgfs/ was introduced), ${FG_HOME} is supposed to point to
FlightGear's install directory, thus it's the same as the install
prefix you enter for Autoconf/CMake.

If you're having everything of FlightGear installed below a single
directory, containing "bin/" for the binaries and "fgdata/" for the
Base Package (or just "data/" before we switched to GIT), then
${FG_HOME} is the variable which is queried for finding the Base
Package at runtime, because it is supposed to reside in
"${FG_HOME}/fgdata/" by definition unless you specify a different
directory by setting ${FG_ROOT}
As a consequence, ${FG_HOME} is supposed _not_ to be writeable.

If it doesn't work this way, I think it's a bug  ;-)

Cheers,
	Martin.
