- Update to upstream version 1.5.5
New ppxopt META variables.
Support for OCAMLFIND_TOOLCHAIN environment variable.

- BuildRequire ocaml-rpm-macros

- BuildRequire at least ocaml 4.02

- Update to upstream version 1.5.3
The installation of "bytes" respects now $prefix and the
configured destination.
New option -pp for "ocamlfind query", to get preprocessor
packages. Updated the compatibility Bytes module to support
extend, init, mapi, blit_string.
- 1.5.2: support for the query formats "%+a" and "%+A".
Fix: the "ppx" property is now also path-expanded when
interpreted in a toploop.
Fix: implicit "ppx" is not path-expanded anymore.
Fix: Build bytes.cmxs only if natdynlink is enabled.
- 1.5.1: includes a file that was missing in 1.5
- 1.5: Including the "bytes" package that is either a compat
package for ocaml < 4.02 or a fake package for ocaml >= 4.02.
The package aims at helping to support the transition to the new
"bytes" type for mutable strings.
Also installing findlib.cmxs if OCaml supports it.
Allowing to disable camlp4 (in prep for OCaml-4.02).
The "ppx" package property can be specified for constructing
ppx-type preprocessor.
- 1.4.1:ocamldoc: The order of -ppopt arguments was changed by
ocamlfind, which is not correct.
- 1.4: Fixed performance bug when many arguments need to be processed.
Auto-configuring ocamldoc.opt if it is found.
New config switch -no-custom to prevent that "ocamlfind" is
linked in custom-runtime mode (bytecode only).
The library dbm is no longer part of OCaml, and now optional in
findlib
Support for ocamloptp.
New function Topfind.log for controlling the verbosity.
Rewritten Fl_metascanner without camlp4
