# remote-bootstrap and remote-add-cross

ifneq (true, $(OMIT_MISC))
# The `remote-bootstrap` goal automates the process of bootstraping MLton on a
# remote machine that doesn't have a suitable pre-compiled `mlton` binary.  It
# works as follows:
#  * send the current sources to a remote machine (using ssh)
#  * build the MLton runtime system on the remote machine
#  * receive the built runtime system from the remote machine as a new target on
#    the host machine
#  * build bootstrap compiler sources on the host machine for the new target
#  * send the boostrap sources to the remote machine
#  * build the boostrap compiler on the remote machine using the boostrap
#    compiler sources
#  * complete the MLton build on the remote machine with the boostrap compiler to
#    obtain a boot package
#  * build MLton on the remote machine from clean sources using the boot package
#  * receive the built binary release from the remote machine
#
# The `remote-add-cross` goal automates the process of adding a cross
# compiler target.  It works as follows:
#  * send the current sources to a remote machine (using ssh)
#  * build the MLton runtime system on the remote machine
#  * receive the built runtime system from the remote machine as a new target on
#    the host machine
#
#
# For both `remote-bootstrap` and `remote-add-cross`, the following `Makefile`
# variables are used:
#  * REMOTE_MACHINE (required): Specify the remote machine to be used as an
#    `ssh` destination, either `[user@]hostname` or
#    `ssh://[user@]hostname[:port]`.
#  * REMOTE_TMP: Specify (absolute) path on remote machine for building; default
#    is `/tmp`.
#  * REMOTE_MAKE: Specify `make` on remote machine.
#  * REMOTE_MAKEFLAGS: Specify `Makefile` variables to set when invoking `make`
#    on the remote machine.
# For `remote-add-cross`, the following additional `Makefile` variable is used:
#  * CROSS_TARGET (required): Specify target machine triple for host
#    cross-compiler; that is the value of `<machine>` in `<machine>-gcc` or
#    `<triple>` in `clang -target=<triple>` on the host machine, such as
#    `arm-linux-gnu`.
#
#
# For example, on OpenBSD, GNU Make is named `gmake` (and `make` is BSD Make)
# and GMP is provided at `/usr/local` (and not on the default search paths).  To
# boostrap on an OpenBSD virtual machine (with localhost port 2222 forwarded to
# guest VM port 22), one could use:
#
# $ make REMOTE_MACHINE=ssh://localhost:2222 REMOTE_MAKE=gmake REMOTE_MAKEFLAGS=WITH_GMP_DIR=/usr/local remote-bootstrap
