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