# It is important to distinguish OCAML_LIBDIR, which points to the

# directory of the ocaml compiler distribution, and OCAMLBUILD_LIBDIR,

# which should be the general library directory of OCaml projects on

# the user machine.

#

# When ocamlbuild was distributed as part of the OCaml compiler

# distribution, there was only one LIBDIR variable, which now

# corresponds to OCAML_LIBDIR.

#

# In particular, plugin compilation would link

# LIBDIR/ocamlbuild/ocamlbuild.cma. For an ocamlbuild distributed as

# part of the compiler distribution, this LIBDIR occurence must be

# interpreted as OCAML_LIBDIR; but with a separate ocamlbuild, it must

# be interpreted as OCAMLBUILD_LIBDIR, as this is where ocamlbuild

# libraries will be installed.

#

# In the generated configuration files, we export

# OCAMLBUILD_{PREFIX,{BIN,LIB,MAN}DIR}, which are the ones that should

# generally be used, as the shorter names PREFIX,{BIN,LIB,MAN}DIR.
