## Makefile for the dOvs CamlJoos 0 compiler
## ---------------------------------------------------------
##
## Usage:
##   make [target]
##
## Targets:
##   joos0.byte     -- build an ocaml byte code joos compiler (default target)
##   joos0.native   -- build an native code joos compiler
##   joos0.top      -- build an interactive joos compiler toplevel
##   joos0.debug    -- build a joos compiler with debugging symbols
##   joos0.profile  -- build a joos compiler with profiling instrumentation
##   htdoc          -- generate documentation (in doc/index.html)
##   libs           -- build and install ocaml library dependencies
##   clean          -- clean up all build related files
