## <NOTE>
## We create dependencies so that packages are built in a certain order.
## (Mostly to make parallel Make work.)
## Currently, we enforce the order in which package sources are listed
## in 'share/make/vars.mk'; we could prepend sources which must come
## first. 
## (Note that this currently starts with 'survival' as this was needed
## by 'boot' at some time: not clear whether this is still true.)

.tgz.ts:
## <FIXME>
## RG says that with FreeBSD Make calling INSTALL does not work without
## explicitly passing down MAKE ('unrecognized option -w ...').  But
## what is really going on?

## <FIXME>
## This no longer seems to be the case?
## survival needs to be installed before boot
## boot.ts: survival.ts boot.tgz
