Anthy -- Japanese Kana-Kanji Conversion Engine Library
						-*- mode:rst -*-

See https://www.nslabs.jp/patch.rhtml

目標1. 分岐したDebian版とFedora版のマージ
  長らくメンテナンスされてきたのは Debian 版だが, Fedora 版は原作者 Yusuke Tabata 氏のヴァージョンから fork しなおしている。修正点も相互に異なっていて、どちらかへの片寄せは簡単ではない。

  | ブランチ         | 元のリポジトリ                                             |
  | ---------------  | -----------------------------------------------------      |
  | upstream_master  | https://salsa.debian.org/debian/anthy/  'master' branch    |
  | anthy-unicode    | https://github.com/fujiwarat/anthy-unicode/  'main' branch |

目標2. ライセンスの整理
  Debian 版には GPLv3, LGPLv3, LGPLv2 の 3つの LICENSE ファイルが添付されているが、トリプルライセンスなのかどうか意図が不明。このファイルの下の方, Licensing セクションとも矛盾している。Fedora 版は LGPLv2 と GPLv2 の mix になっている。
  元々のヴァージョンでは, Anthy には LGPLv2 が適用され, 辞書ファイルである alt-cannadic には GPLv2 が適用されていた。これを雑に一つのパッケージにまとめていたのが不味い。Debian 版はさらに混乱して、誤って (LGPL ではなく) GPLv3 を添付したのだろう (でないと下の記述と合わない).
  現代の流儀だと, Anthy パッケージと, alt-cannadic から Anthy 形式の辞書を作るパッケージの二つに分割し、前者には LGPL を適用するのが意図をきちんと反映することになる。Debian 由来のコードを含むので, LGPLv3 (LGPLv2 ではなく) か.

目標3. Windows へのポーティング
  GUI ではないのにべったり UNIX に依存している. ポータブルなコードに修正する。
  -> ビルドは通る。テスト未了.

ライセンスもコードの品質も正直微妙だが、他方, Canna は古すぎて現代の環境でコンパイルすら難しい。Anthy ぐらいしか選択肢がない。トホホ


  
What's Anthy?
=============

Anthy is a library for Japanese Kana-Kanji conversion, targeted for
Japanese text input.

See following page for Anthy development:
	http://wiki.debian.org/Teams/DebianAnthy
	http://git.debian.org/?p=pkg-anthy/anthy.git;a=summary


What's New?
===========

See the file NEWS for new features and other user-visible changes in
recent versions of Anthy.


Installation
============

The file INSTALL says how to build and install Anhty on your system.


Configuration 
=============

System administrator is expected to set up following three variables
in anthy-conf.in (usually it's under /etc/anthy directory).

    Variable name  Example                         # Comment
    ----------------------------------------------------------------
    ANTHYDIR       /usr/share/anthy                # Directory 
    DIC_FILE       /usr/share/anthy/anthy.dic      # Dictionary file
    ZIPDICT        /usr/share/anthy/dic/zipcode.t  # Zipcode file


Anthy Dictionary (anthy.dic)
============================

Here is a figure to explain how Anthy Dictionary (anthy.dic) is
generated.

   depgraph/*.depword
   depgraph/conjugate.table
    ---[depgraph/mkdepgraph]---> anthy.dep (1)

   mkworddic/{extra.t,compound.t,adjust.t,utf8.t,udict},
   alt-cannadic/{gcanna.ctd,gcannf.ctd,gtankan.ctd,g_fname.t}
    ---[mkworddic/mkworddic]---> anthy.wdic (2)

   "initial anthy.dic"
   corpus/corpus.?.txt
    ---[calctrans/{proccorpus,calctrans}]---> corpus_info (3-1)
    					      weak_words  (3-2)

      calctrans/{corpus_info,weak_words} (3-1,3-2)
       ---[calctrans/calctrans]---> anthy.cand_info (3)
       				    anthy.trans_info (4)
				    anthy.corpus_array (5)
				    anthy.corpus_bucket (6)
      				    anthy.weak_words (7)

         (1) depgraph/anthy.dep
         (2) mkworddic/anthy.wdic
         (3) calctrans/anthy.cand_info
         (4) calctrans/anthy.trans_info
         (5) calctrans/anthy.corpus_array
         (6) calctrans/anthy.corpus_bucket
         (7) calctrans/anthy.weak_words
          ---[mkanthydic/mkfiledic]--->anthy.dic

Note that we need "initial anthy.dic" to generate anthy.dic, that's
because 'proccorpus' uses Anthy Dictionary to parse text input.

Public Licence 3 (or later), i.e., LGPLv3+.  See the file COPYING.LIB

History
=======

Anthy project was hosted at SourceForge.JP.

	http://anthy.sourceforge.jp/
	http://anthy.sourceforge.jp/cgi-bin/hiki/hiki.cgi

Since February 2009, development at there stopped.  Bug fixes and
feature requests was just floating around.

In May 2010, NIIBE Yutaka <gniibe@fsij.org> arranged Git repository at
git.debian.org, put some of released versions of Anthy and Debian
packaging code into the repository, and took over the development
lead.  At alioth.debian.org, pkg-anthy project was created for Anthy
development and Debian packaging for Anthy and related packages.
