The *.sources is a read-only file, so it is first searched in VM path
where it is protected from accidental modifications and caters to the
case when the same VM is used to run images located in multiple
directories. It is part of the image, so it could also be placed in the
image directory if VM path is not writable (multi-user case). This will
get the beginners started quickly with minimum fuss.
For more advanced uses, we could change the image to look for an
override, say $SQUEAK_SOURCES, to override these hard-coded paths.
Or, we could place sources file in $HOME/.squeak/ and symlink it from
different image directories. This can be added to the launch script.
SQUEAK_SOURCES=....
IMAGE_DIR=...
VM_DIR=...
ensure_sources() {
test -f $VM_DIR/$1 || \
test -f $IMAGE_DIR/$1 || \
ln -s "$HOME/.squeak/$1" "$IMAGE_DIR/$1"
}
ensure_sources $SQUEAK_SOURCES
