Signature for configurable module implementations. A
configurable is a module implementation which contains a runtime state which can be set either at configuration time (by the application builder) or at runtime, using command-line arguments.
method ty : 'ty typ
ty is the module type of the configurable.
packages is the list of OPAM packages which needs to be installed before compiling the configurable.
method connect : Info.t -> string -> string list -> string
connect info mod args is the code to execute in order to initialize the state associated with the module
mod (usually calling
mod.connect) with the arguments
args, in the context of the project information
configure info is the code to execute in order to configure the device. During the configuration phase, the specficied
packages might not yet be there. The code might involve generating more OCaml code, running shell scripts, etc.
build info is the code to execute in order to build the device. During the build phase, you can rely that all
packages are installed (via opam). The code might involve generating more OCaml code (crunching directories), running shell scripts, etc.
clean info is the code to clean-up what has been generated by
method keys : key list
keys is the list of command-line keys to set-up the configurable.
method deps : abstract_impl list
deps is the list of abstract implementations that must be initialized before calling
