  * Version 0.4.8

  * Major changes:

    * Fix various problems of parsing present in OASIS 0.4.7:
      * Only issue a warning when extraneous blanks are present. (Closes: #1665)
      * Fixes ocamlbuild plugin argument handling bug. (Closes: #1659)
      * Re-add MyOCamlbuildBase.env_filename.
      * Script to test reverse build depends (Closes: #1672).

    * Enable creation of OASIS plugin and OASIS command line plugin:
      * Add examples/plugins to demonstrate how to build plugins.
      * Update HACKING.md.
      * Ensure they work, using a test.

    * Plugin "omake":
      * Workaround for a problem in omake-0.9.8.6: variables accumulated
        via foreach cannot be private.
      * Passing the title string down to ocamldoc
      * Fix compilation of pack-level mli's.
      * Move definition of some variables in subdirectories to use them
        correctly (OCAMLINCLUDES, OCAMLPACKS and a few others)

    Thanks to Gerd Stolpmann for these contributions.

    * Improve CI/tests:
      * Split quickstart tests out of the main tests, because it fails too
        often and often need to be disabled.
      * Reorganize test/ directories.
      * Use OCaml 4.04 for Travis-CI.
      * Reorganize my CI scripts in src/tools/ci.
      * Get rid of ardivink and switch to OPAM for travis and jenkins builders.

    * Create 2 branches (opam/unstable and opam/testing) to provide pinning
      capabilities to OPAM:
      * It allows OPAM to track the development version of OASIS
      * Update information in README.md
      * Add a makefile target to allow to create opam/ in a local copy for
        testing a locally hacked version of OASIS.
      * Setup auto-generation of opam/unstable branch and auto-promotion of
        opam/unstable to opam/testing when integration tests have succeeded.

  * Minor changes:
    * Quick hack to solve #1674 and allow to use flambda, upstream notified of
      the problem. (Closes: #1674)
    * Use OASISFormat 0.4 for OASIS itself:
      * Use source_patterns feature to precisely locate .mlify files.
      * Use markdown to generate standard files.
      * Add BugReports to generated README in StdFiles.

Thanks to Edwin Török, Yuri D. Lensky and Gerd Stolpmann for their
contributions.

  * Version 0.4.7

  * Drop support for OASISFormat 0.2 and 0.1.

    As per the version policy in HACKING.md, this change syncs with OASIS
    version in Debian. Debian Jessie has OASIS v0.4.4, so it is possible to
    drop support for older version.

  * Provide stable API in setup.ml using BaseCompat.

    This change introduces BaseCompat and opens by default the version
    matching OASISFormat in setup.ml. This allows to make changes to OASIS
    and still provides a stable API in setup.ml. The only side effect is that
    it requires to update the setup.ml of DynRun at every major version updates.

    Unfortunately, providing compatibility for ALL changes is an hard task.
    Users are welcome to file bugs whenever their customized setup.ml breaks
    because of an incompatible change.

  * Plugin "omake":

    This new plugin provides build, doc and install capabilities using
    OMake. Some features are not supported, like Object sections.
    It requires 'OCamlVersion: >= 4.01'.

    Example:
      OASISFormat:  0.4
      OCamlVersion: >= 4.01
      [...]
      BuildTools:   omake
      BuildType:    omake (0.4)

      Library simplelib
        [...]

      Document simplelib
        BuildTools+:     ocamldoc
        [...]

    Thanks to Gerd Stolpmann for this huge contribution.

  * Create OASIFileSystem and use it in OASISContext.t.srcfs.

    The new module OASISFileSystem is a filesystem abstraction layer that
    allows to better represents (through types) where the files are (e.g.
    source or build directory).

    The very first use of it is to add in OASISContext.t as srcfs. The
    filesystem object is itself limited to only use
    OASISContext.source_filename, which allows to use types to enforce
    location of files.

    The various default_filename across the code are now typed according to
    their location (e.g. "setup.log" and "setup.data" are
    OASISContext.source_filename). The only way to actually open, read and
    write the corresponding file is to apply methods provided in OASISFileSystem
    object.

    This change also delays enough the evaluation of the location of
    "setup.log" and "setup.data", which solves the bug 1473.
    (Closes: #1473)

  * Improve automatic tests:
    * Use OPAM to install dependencies.
    * Use Travis to test and compile with all major OCaml version since 3.12.1
      on Linux.
    * Use AppVeyor to compile on Cygwin.
    * Test for dynamic mode mode compilation on Cygwin with AppVeyor.
    * Rename test files to reflect what files they are testing.
    * Split test/data/TestFull/* tests to reflect what plugins/files they are
      testing.
    * Add some badges for build status on Travis and AppVeyor in README.md.
    * Test the parsing of examples/oasis/*.oasis files.
    * Check all examples are tested, add examples/ocamlbuild tests.
    * Check that all examples use the latest version of OASIS.
    * Disable test 'external source rebuild' which tends to be flaky.
    * Refactor TestFull to remove boilerplates and make it more readable.
    * Create a test function to check all subdirectories are listed and tested,
      add tests for the missing ones.
    * Reduce the number of skipped tests.
    * Refine constraint to produce .cmt to >=4.01.

  * Trim down the dependencies:
    * Stop depending on ocaml-data-notation and type_conv.
    * Create a trim down, internval version of ocaml-data-notation. The
      conversion functions  need to be manually written -- not perfect
      but a good way to drop the dependency and still be compatible with OCaml
      3.12.1.
    * Stop depending on ocaml-gettext, this was never really used.
    * Get rid of camlp4:
      * Replace most genlex parser, by standard yacc/lex parsers.
      * Replace OASISRecDescParser by OASISAst_parser using ocamlyacc.
        (Closes: #298)
      * The "flag(...)" in expression is now case sensitive, to avoid conflict
        with the "Flag ..." section.
      * Some parts still use Genlex, but don't need camlp4 anymore.
    * Trimming down the dependencies allows to make it easier to port OASIS on
      other platforms (like Windows) where some former dependencies were tricky
      to compile (like camlp4).

  * Stop using -install-lib-dir on Windows.

    This change prevents the use of -install-lib-dir on Windows, for OCaml
    version greater than 3.11.1. The bug in ocamlbuild has been fixed in OCaml
    3.11.1 [1]. This is a bit a shot in the dark, since testing on Windows is
    not setup.

  * Minor changes:
    * Consistently use choices type in OASISExpr module.
    * Make OCamlbuild plugin not assume that dynamic linking is supported.
      (Patch: #1536) (Closes: #1251)
    * Improve setup.log parsing, by using Genlex.
    * Enforce using a published version of OASIS to generate its own setup.ml,
      provide explanations in HACKING.md.
    * Fix problem reading files on Cygwin (esp. setup.log), reported size after
      an append doesn't reflect the real size of the file in some cases.
    * Always compile src/tools/* and move dist.ml there.
    * Refactor string version comparison into its own sub-module.
    * Fix missing rules for headache.
    * Remove unused userconf library.
    * Pass -thread to C files as well.
    * Don't use $< in explicit DevFiles build rule (BSD make compatibility).
    * Example to override cc when compiling C source files.
    * Remove the need for Bytes altogether.
    * Add fields "Tags" and "BugReports" to export them to OPAM.
    * Big documentation cleanup (`\_oasis` synopsis, doc/*).
    * Reformat source files using ocp-indent and start to use merlin.
    * Allow to use a string when testing values in `\_oasis`, for example it is
      now possible to use expression like 'ocaml_version("4.02.1")'
    * Improve OASISVersion.comparator_reduce. Now, it transforms the given
      comparator into its disjunctive form and order the version number.
    * Rename all executables so that their names match OCaml policy for module.
    * Move all executables into their own directories to prevent dependencies
      leak.
    * Transform tools into executables.
    * Always compile executables to check they still work.


  * Features:

    * no_automatic_syntax (alpha): don't disable the -package injection logic.

    * compiled_setup_ml (alpha):
      * Fix the configure file when using the compiled_setup_ml feature and
        improve the Makefile.
      * Recompile when needed while executing the configure script.

    * findlib_directory (beta, new):

      Findlib allows to specify a "directory" in a META file. This can be used
      to store some files of the library in sub-directories. This change
      allows to set and use this "directory" field.

      The InternalInstall plugin now handles installing files in
      sub-directories.  However there is no flag to specify this when using
      `ocamlfind install`, so we use a standard file installation, with a
      best-guess computation of the target directory.

      The META plugin can now set the "directory" field according to what has
      been set in the `_oasis` file. Note that, for nested package the install
      directory is relative to the install directory of the parent package.

      Example:
        BetaFeatures: findlib_directory
        Plugins: META(0.4)

        Library library
          [...]
          FindlibDirectory: lib

      Thanks to Gabriel Radanne for this contribution. (Closes: #1305)

    * findlib_extra_files (beta, new):

      This change allows to use a new `_oasis` field 'FindlibExtraFiles' to
      install extra files along the matching library/object in findlib.

      Example:
        BetaFeatures: findlib_extra_files

        Library library
          [...]
          FindlibName: foobar
          FindlibExtraFiles: myfile.txt

      In this case `myfile.txt` will be installed in the same directory as the
      'foobar' package.

      Thanks to Evgenii Lepikhin for the contribution. (Closes: #802)

    * source_patterns (alpha, new):

      This change allows to override the built-in source files search. It uses
      user-provided 'InterfacePatterns' and 'ImplementationPatterns' fields and
      a small DSL to define how to find a file matching a given module. The
      fields can be defined at the top level or in the Library section.

      The DSL is based on Genlex and Buffer.add_substitute. It has two
      functions `capitalize_file` and `uncapitalize_file` and one variable
      `module`.

      Example:
        AlphaFeatures: source_patterns

        Library library
          [...]
          Modules: FooBar
          InterfacePatterns+: ${module}.eliomi
          ImplementationPatterns+:  ${module}.eliom

      It is particularly useful to get rid of the warnings like:
      W: Cannot find source file matching module [...]

      Thanks to Petter Urkedal for this contribution.

2016-04-29  Sylvain Le Gall <sylvain AT le-gall.net>

  * Version 0.4.6

  * Hotfix release for OCaml 4.03.0 (Closes: #1519).

  * Major changes:

   * Create patch functions to mimic the new String.lowercase_ascii,
     String.uppercase_ascii, String.capitalize_ascii and
     String.uncapitalize_ascii found in OCaml 4.03.0
   * Disable tests depending on not yet buildable units with OCaml 4.03.0 (e.g.
     expect which depends on batteries, which doesn't yet compile)
   * Minimal version of OCaml is now 3.12.1. (Debian Wheezy version)


2014-10-22  Jacques-Pascal Deplaix <jp.deplaix AT gmail.com>

  * Version 0.4.5

  * Major changes:

    * Build and install annotation files.
    * Use builtin bin_annot and annot tags.
    * Tag .mly files on the same basis as .ml and .mli files
      (required by menhir).
    * Remove 'program' constraint from C-dependencies.
      Currently, when a library has C-sources and e.g. an executable
      depends on that library, then changing the C-sources and running
      '-build' does not yield a rebuild of the library.
      By adding these dependencies (rather removing the constraint),
      it seems to work fine.


  * Minor changes:

    * Add tests tag if --enable-tests.
    * Remove ocaml 4.02 warnings.
    * Fix the automatic use of -syntax for OCamlVersion >= 3.12.1.
    * Use the right ocamlfind binary to get all supported packages.
      The name of the ocamlfind binary should be read from the configuration.
      This is especially useful when cross-compiling.

  * Features:

    * no_automatic_syntax (alpha): Disable the automatic inclusion
      of -syntax camlp4o for packages that matches the internal heuristic
      (if a dependency ends with a .syntax or is a well known syntax).

    * compiled_setup_ml (alpha): Fix a bug using multiple arguments
      to the configure script.


  Thanks to Christopher Zimmermann, Jerome Vouillon, Tomohiro Matsuyama
  and Christoph Höger for their pull requests and to help release this version.


2014-03-26  Sylvain Le Gall <sylvain AT le-gall.net>

  * Version 0.4.4

  * Quick bug fix release:

    * Don't skip some "\n\n" in Makefile/META/myocamlbuild.ml/setup.ml. This
      bug makes `oasis setup` think that these files have changed even if they
      have just been regenerated. (Closes: #1382).


2014-03-25  Sylvain Le Gall <sylvain AT le-gall.net>

  * Version 0.4.3

  * Major changes:

    * Added -remove switch to the setup-clean subcommand designed to remove
      unaltered generated files completely, rather than simply emptying their
      OASIS section.
    * Translate path of ocamlfind on Windows to be bash/win32 friendly.
    * Description is now parsed in a more structured text (para/verbatim).

  * Minor changes:

    * Give a more precise message when module name are wrong (Closes: #1236).
    * Prevent loop in transitive_closure computation (Closes: #1253).
    * Update HACKING.md to define how to do a release and add some version
      and backward compatibility requirements.
    * No timeout for ocaml-expect, to prevent flaky tests on slow architecture.
    * Prevent warnings from confusing the terminal, add some extra \n.
    * Force to use the ocamlfind define in configure. (Closes: #1360)
    * Add more descriptive message when indentation is wrong (Closes: #1295)

  * Features:

    * stdfiles_markdown (alpha): set default extension of StdFiles (AUTHORS,
      INSTALL, README) tp be '.md'. Use markdown syntax for standard files. Use
      comments that hides OASIS section and digest. This feature should help
      direct publishing on GitHub.

    * disable_oasis_section (alpha): it allows DisableOASISSection to be
      specified in the package with a list of expandable filenames given. Any
      generated file specified in this list doesn't get an OASIS section digest
      or comment headers and footers and is therefore regenerated each time
      oasis setup is run (and any changes made are lost).
      This feature is mainly intended for use with StdFiles so that, for
      example, INSTALL.txt and AUTHORS.txt (which often won't be modified) can
      have the extra comment lines removed.

    * compiled_setup_ml (alpha): allow to precompile setup.ml to speedup.


  Thanks to David Allsopp, Martin Keegan and Jacques-Pascal Deplaix for their
  pull requests and to help release this version.


2014-02-23  Sylvain Le Gall <sylvain AT le-gall.net>

  * Version 0.4.2

  * Major changes:

    * Change BSD3 and BSD4 to BSD-3-clause and BSD-4-clause to comply with
      DEP5, add BSD-2-clause. BSD3 and BSD4 are still valid but marked as
      deprecated.
      More information:
      http://dep.debian.net/deps/dep5/#license-specification

    * Enhance .cmxs supports through the generation of .mldylib files.
      When one of the modules of a library has the name of the library,
      ocamlbuild tends to just transform this module into a .cmxs. Now, the use
      of a .mldylib fix that problem and the .cmxs really contains all modules
      of the library.

    * Refactor oasis.cli to be able to create subcommand plugins.
      * Exported modules starts now with CLI.
      * Display plugins in the manual.
      * Design so that it is possible to be thread-safe.
      * Try to minimize the number of functions.
      * Make better choice of name and API.
      * A subcommand plugin 'dist' to create tarball is in preparation, as a
        separate project.

    * Remove plugin-list subcommand, this command was limited and probably not
      used. A better alternative will appear in next version.

    * Sub-command setup-dev is now hidden and will soon be removed.

  * Minor changes:

    * Refactor ocamlbuild build plugin to have some features in doc plugin.
      XOCamlbuilExtraArgs and XOCamlbuildPluginTags are now available for
      Document. The flag '-use-ocamlfind' is set for doc and build plugin.

    * Reorganize the test/data directory, each toplevel test has now its
      dedicated subdirectory in test/data.

    * Start to work on better support of syntax extension:
      * Remove archive(syntax,{byte,native}) from the META, this was causing
        an issue when trying to compile.
      * Add an example that creates a syntax extension.
      * Add support for auto-guessing syntax_camlp4o when one of the syntax
        extension shipped with camlp4 is in a build depends.

    * Allow to include $(X) in CCOpt/CClib.
      This patch helps to enable variable susbtitution for flags. This allow to
      write a PostConfCommand script to insert this data in setup.data and have
      them back when running OCamlbuild.

    * Raise error when "true" or "false" are not spelled correctly.

    * Fix some warnings about "Field X is set but matcing plugin Z is not
      enabled."

  Thanks to Andrew Ferguson, Florent Monnier and Jacques-Pascal Deplaix for
  their pull requests and to help release this version.


2013-12-19  Sylvain Le Gall <sylvain AT le-gall.net>

  * Version 0.4.1

  * Major changes:

     * Fix broken compilation with threads and OCaml >= 4.01 (Closes: #1358)

  * Minor changes:

    * Refactor plugins for command line interface.
    * Get rid of message 'field is set but no matching plugin'
      (Closes: #795, #1043).

  * Features:

    * dynrun_for_release (alpha):
      * The goal of this plugin is to allow creating release with a minimal
        setup.ml that uses '-setup-update dynamic'.
      * Refactor setup.ml to perform early checks. like looking for findlib
        and oasis.dynrun library and warns the user in case they cannot be
        found (early configure script).
      * Along setup.ml, Makefile and configure, also keep INSTALL.txt if
        StdFiles plugins is used to provide a readable list of package to
        install.

  * Addendum to 0.4.0 release:
    * Since 0.4.0 OASIS has a limited support to syntax extension. If in the
      list of BuildDepends, one of the library ends with ".syntax", OASIS will
      add the tag "syntax_camlp4o" to all files of this library. This new
       feature already covers some common case of using syntax extensions.


2013-12-13  Sylvain Le Gall <sylvain AT le-gall.net>

  * Version 0.4.0

  * Major changes:

     * Migrate the source repository to https://github.com/ocaml/oasis
     * Fix a lot of code style issues (e.g. blank at the end of the line) and
       create a test to check that the style of generated files is correct. Some
       related tools has been fixed asi well, for the best formatting use
       ocamlmod >= 0.0.7 and ocaml-data-notation >= 0.0.10.
     * Port all tests to OUnit 2.0, which allows to run all tests faster.
     * Run some tests with a fake bytecode only setup, so that we can always
       check that bytecode and nativecode tests are passing.  (Closes: #1306)
     * Fix a missing dependency on ocamlbuild package and inclusion of
       ocambuildlib.cma in builtin-plugins.cma.
     * Introduce a framework to create features.
       * Add fields AlphaFeatures and BetaFeatures to list the experimental
         features you want to use in your _oasis
       * Using AlphaFeatures and BetaFeatures is only allowed if OASISFormat is
         set to the latest OASIS version. There is no backward compatiblity for
         experimental features. For example, if you are using OASIS 0.4.X,
         OASISFormat must be set to 0.4.
       * AlphaFeatures represents features not fully completed that maybe very
         unstable, quickly evolving and even removed in future release.
       * BetaFeatures represents features almost finished that needs to mature
         a bit before being published.
       * See 'Features' section in this changelog to have a list of what
         features are available.

  * Minor changes:
     * Self compile during tests.
     * Apply patches found in vouillon/opam-android-repository.
     * Fix bug when a directory with the right name appears in the PATH.
     * Fix OASISPath_intern.fn_reader on Cygwin.
     * Fix suffix_program on Cygwin.
     * Fix the META generation when XMETAType: syntax.
     * Fix for installing .cmx files with packed libraries as required for
       cross-module inlining.
     * Fix bad location of .cmx generated along .cmxs.
     * Add GNU Affero GPL license
     * Add the wtfpl license
     * Fix typos, thanks to Hendrik Tews.
     * Locate "topfind" when using opam "system" compiler.
     * Fix issue (Closes: #1239)
     * Assume camlp4o when packages end in .syntax.
     * Make sure the right Findlib version is used with OCaml 4.0.0.
     * Fix strange split function in myocamlbuild (Closes: #1186)

  * Features:

     * section_object (beta):
        * Implement 'Object' section, thanks to Philippe Veber

     * pure_interface (alpha):
        * Support pure interface modules in libraries.

     * ocamlbuild_more_args (alpha):
        * Add field XOCamlbuildPluginTags to pass -plugin-tags to OCamlbuild
        * Add field XOCamlbuildExtraArgs to pass more args to OCamlbuild


2012-06-28  Sylvain Le Gall <sylvain AT le-gall.net>

  * Version 0.3.0

  * EXTREMLY IMPORTANT changes (read this):

    * Fix bug with scanf %S@\n for ocaml 4.00. We were unfortunetaly using an
      undocumented tolerance of Scanf in the previous version. You should
      consider making new release using this version that fixed this.

      PACKAGES uploaded to oasis-db will be automatically "derived" before
      OCaml 4.00 release (i.e.  oUnit v1.1.1 will be regenerated with this new
      version as oUnit v1.1.1~oasis1).

      PACKAGES not uploaded to oasis-db need to be regenerated. In order not to
      break 3rd party tools that consider a tarball constant, I recommend to
      create a new version.

      Thanks to INRIA OCaml team for synchronizing with us on this point.

  * Major changes:

    * Handle the field "Pack: true" to be able to create packed libraries. It
      also installs .mli files for documentation into the target directory.
      The pack option is only supported for "OASISFormat: 0.3", you will need
      to update the version of your _oasis file to match it.


    * Introduce --[enable|disable]-[tests|docs] to disable tests and docs at
      oasis level. It seems a very common pattern to have a "Flag tests" to
      turn off by default the tests. This is now define as a standard var and
      you should remove you previous "Flag tests" but you can continue to
      use "flag(tests)" where needed.

      You can now have the following example:
      ...

      Executable test_exec
        Install: false
        Build$: flag(tests)
        MainIs: testExec.ml
        BuildDepends: oUnit

      Test main
        Command: $test_exec
        TestTools: test_exec

      ...

      The "Run$: flag(tests)" is implicit for the section "Test main". The
      default value is "false" for tests. If all the executable for test are
      flagged correctly (Build$: flag(tests)), you'll get rid of the dependency
      on oUnit.

      It works the same for documentation, however the default is "true".
      (Closes: #866)

    * Allow to define interdependent flags

       In order to allow interdependent flags, we transform back lazy values
       into 'unit -> string' functions. This allows to change a flag value on
       the command line and to update all the dependent values.
       (Closes: #827, #938)

    * Deprecate the subcommand 'oasis setup-dev' in favor of
      'oasis setup -setup-update {none|weak|dynamic}'

      It defines different ways to manage the auto-update of setup.ml:
      * 'none': this is the default mode, and the one you should use when
         distributing tarballs. No update are performed at al.
      * 'weak': the update is only triggered when something change in `_oasis`,
         we keep all files generated
      * 'dynamic': the content of 'setup.ml' is ultra small (<2kB) and we only
         keep a small 'setup.ml', 'Makefile' and 'configure'.

      The choice between 'weak' and 'dynamic' depends on your need with
      regard to VCS and to the presence of `oasis'. The 'weak' allow to checkout
      the project from VCS and be able to work on it, without the need of
      installing 'oasis' as long as you don't change the file '_oasis'. But it
      clutter your VCS history with changes to the build system each time you
      change something in '_oasis'. The 'dynamic' mode gives you no VCS history
      pollution but makes mandatory to have installed oasis libraries.

    * Don't copy executable in ocamlbuild

      Avoid copying executable to their real name. It helps to call ocamlbuild a
      single time for the whole build rather than calling it n time (n = number
      of executable sections) and copying resulting exec.

      This speeds up the build process because ocamlbuild doesn't have to
      compute/scan dependencies each time.

      The drawback is that you have to use $foo when you want to call
      "Executable foo", because $foo will be _build/.../main.byte.

    * Change the way we parse command line like option (CCOpt, CCLib and the
      like). We have implemented a real POSIX command line parser, except that
      variables are processed by Buffer.add_substitute (except if correctly
      escaped, using Buffer.add_substitute escaping).

      Example:
        CCOpt: -DEXTERNAL_EXP10 -L/sw/lib "-framework vecLib"

      Will be parsed correctly and outputed according to target OS.

    * Externalize ocamlmod in its own project, which become a dependencies.

    * Minimize the dependencies of the project.

      In order to ease building oasis, we have minimize the number of
      dependencies.  You only need to install ocamlmod, ocamlify and
      ocaml-data-notation for a standard build without tests. Dependencies on
      pcre, extlib and ocamlgraph has been dropped. The remaining dependencies
      are hidden behind a flag "tests".

    * Implement proposal for handling plugin in META, using "plugin" extra
      directives

      oasis now produces .cmxs file by default and add them to META.

      Now a META looks like:

      ...
      archive(byte) = "oasis.cma"
      archive(byte, plugin) = "oasis.cma"
      archive(native) = "oasis.cmxa"
      archive(native, plugin) = "oasis.cmxs"
      ...

      This will ultimately help to generate automatically .cmxs for all oasis
      enabled projects. We hope that this new feature will improve dynamic
      linking use in OCaml (esp. for project like Ocsigen).

    Thanks to Anil Madhavapeddy, Pierre Chambart, Christophe Troestler,
    Jeremie Dimino, Ronan Le Hy, Yaron Minsky and Till Varoquaux for their help
    with this release.

    Also thanks to all the testers of the numerous release candidates. This
    was a long work and each time a tester has downloaded oasis has helped me
    to know that I was working for someone.

2010-10-16  Sylvain Le Gall <sylvain.le-gall AT ocamlcore.com>

  * Version 0.2.0

  * Split the project into 3 libraries and one executable:
    * oasis: the core library
    * oasis.base: the runtime library
    * oasis.builtin-plugins: various plugins (ocamlbuild, internal, none,
      custom)
    * the executable 'oasis' in lowercase which was 'OASIS' before
      (Closes: #769)

  * Publish .mli and improve ocamldoc generated documentation (Closes: #667)

  * oasis library:
    * Ignore plugins even when parsing field
    * Allow to redirect messages through a function and use a context to avoid
      global variables. This is an OASIS-DB website requirement, but we fallback
      to a global variable in oasis.base
    * Use the same policy as Debian for version comparison (copied from dpkg)
      (Closes: #584)
    * Add MIT, CeCILL licenses and make unknown license less fatal
      (Closes: #710, #557)
    * Allow https, ftp, mailto, svn, svn+ssh for URL (Closes: #753)
    * Replace Str by Pcre
    * Don't modify package data structure through plugins, we just issue
      warnings and error when something is missing. This is compensated by a
      better 'quickstart' that can automatically complete required fields (e.g.
      it adds 'ocamlbuild' as a BuildDependency for 'ocamlbuild' plugin).
      (Closes: #552, #566)
    * Set default for test type to 'custom' plugin (Closes: #562)
    * Use a more simple lexer for _oasis (Closes: #579)
    * Warn if the use of '\t' to indent lines is inconsistent in an _oasis file
      (e.g. mix of ' ' and '\t')
    * Allow to use 'flag' as environment variables in _oasis (e.g. flag test
      can be used as Command: echo $test) (Closes: #619)
    * ADVANCED USERS: Create a new scheme to synchronize data between the
      property list used to parse and print an _oasis file and the data
      structure representing it. This is a first step to avoid carrying
      property lists inside the data structure.  It should also allow to dump
      plugin data directly inside the data structure rather than having to do
      it "by hand". This allows to have a more complete quickstart support
      also (i.e. handling plugins directly). It also allows to manipulate the
      datastructures in a single place: with the scheme before you have to
      update the property list and the rest of the datastructure. (Closes:
      #705, #733)

  * oasis.base library:
    * Exit with an error code when tests fail
    * Don't account skipped test (Closes: #624)
    * Delegate the "setup-dev" actions to the executable 'oasis' rather than
      embedding it into setup.ml
    * Add a '-version' to setup.ml to know what version has generated the file
      (Closes: #692)
    * Add a '-all' target that does "-configure", "-build", "-doc" and "-test"
      in one run (Closes: #551)
    * Add a '-reinstall' target that 'uninstall' and 'install' (Closes: #568)
    * Use the right command to delete file on Windows

  * executable 'oasis':
    * Use a subcommand scheme, like subversion. For example, it replaces the
      former "OASIS -setup" by "oasis setup". Each subcommand can be a small
      plugin
    * Add a "query" subcommand to extract data of _oasis from command line
      (Closes: #691)
    * Add a "setup-clean" subcommand that removes generated files and helps
      cleaning OASIS_START/STOP section of their content
      (Closes: #564, #623, #563)
    * Add a "check" subcommend that checks _oasis files
    * Greatly improve the "quickstart" subcommand:
      * Take into account plugins in quickstart
      * Allow to have multiple choices for field Plugins in quickstart mode
      * Don't display help text at each question (Closes: #586)
      * Allow to create a doc (Closes: #633)
      * Allow to run a pager, editor or "oasis setup-dev" at the end
        (Closes: #580, #582)
      * Don't accept '?' as an answer in quickstart (Closes: #587)
      * Add examples and all available licenses in the help of License field
        (Closes: #559)
    * Keep generated files when 'oasis setup-dev' is called (Closes: #743)

  * Plugin "ocamlbuild":
    * Handle "Path: ." in generated _tags correctly (Closes: #570, #588)
    * Quick fix to handle .h files directly in CSources field
    * Include .mli in _tags (Closes: #572)
    * Pass -cclib and -dllpath options to ocamlmklib  (Closes: #629)
    * Don't pass -dlllib and -dllpath options to ocamlopt (Closes: #628)

  * Plugin "internal":
    * Create parent directories when installing with InternalInstall
      (Closes: #555)
    * Don't install data when section is not built (Closes: #554, #556)

  * Plugin "META":
    * Add an exists_if field to generated META file (Closes: #694)
