+     The Initial Developer hereby grants You a world-wide, royalty-free,
+     non-exclusive license, subject to third party intellectual property
+     claims:
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Initial Developer to use, reproduce,
+          modify, display, perform, sublicense and distribute the Original
+          Code (or portions thereof) with or without Modifications, and/or
+          as part of a Larger Work; and
+
+          (b) under Patents Claims infringed by the making, using or
+          selling of Original Code, to make, have made, use, practice,
+          sell, and offer for sale, and/or otherwise dispose of the
+          Original Code (or portions thereof).
+
+          (c) the licenses granted in this Section 2.1(a) and (b) are
+          effective on the date Initial Developer first distributes
+          Original Code under the terms of this License.
+
+          (d) Notwithstanding Section 2.1(b) above, no patent license is
+          granted: 1) for code that You delete from the Original Code; 2)
+          separate from the Original Code;  or 3) for infringements caused
+          by: i) the modification of the Original Code or ii) the
+          combination of the Original Code with other software or devices.
+
+     2.2. Contributor Grant.
+     Subject to third party intellectual property claims, each Contributor
+     hereby grants You a world-wide, royalty-free, non-exclusive license
+
+          (a)  under intellectual property rights (other than patent or
+          trademark) Licensable by Contributor, to use, reproduce, modify,
+          display, perform, sublicense and distribute the Modifications
+          created by such Contributor (or portions thereof) either on an
+          unmodified basis, with other Modifications, as Covered Code
+          and/or as part of a Larger Work; and
+
+          (b) under Patent Claims infringed by the making, using, or
+          selling of  Modifications made by that Contributor either alone
+          and/or in combination with its Contributor Version (or portions
+          of such combination), to make, use, sell, offer for sale, have
+          made, and/or otherwise dispose of: 1) Modifications made by that
+          Contributor (or portions thereof); and 2) the combination of
+          Modifications made by that Contributor with its Contributor
+          Version (or portions of such combination).
+
+          (c) the licenses granted in Sections 2.2(a) and 2.2(b) are
+          effective on the date Contributor first makes Commercial Use of
+          the Covered Code.
+
+          (d)    Notwithstanding Section 2.2(b) above, no patent license is
+          granted: 1) for any code that Contributor has deleted from the
+          Contributor Version; 2)  separate from the Contributor Version;
+          3)  for infringements caused by: i) third party modifications of
+          Contributor Version or ii)  the combination of Modifications made
+          by that Contributor with other software  (except as part of the
+          Contributor Version) or other devices; or 4) under Patent Claims
+          infringed by Covered Code in the absence of Modifications made by
+          that Contributor.
+
+3. Distribution Obligations.
+
+     3.1. Application of License.
+     The Modifications which You create or to which You contribute are
+     governed by the terms of this License, including without limitation
+     Section 2.2. The Source Code version of Covered Code may be
+     distributed only under the terms of this License or a future version
+     of this License released under Section 6.1, and You must include a
+     copy of this License with every copy of the Source Code You
+     distribute. You may not offer or impose any terms on any Source Code
+     version that alters or restricts the applicable version of this
+     License or the recipients' rights hereunder. However, You may include
+     an additional document offering the additional rights described in
+     Section 3.5.
+
+     3.2. Availability of Source Code.
+     Any Modification which You create or to which You contribute must be
+     made available in Source Code form under the terms of this License
+     either on the same media as an Executable version or via an accepted
+     Electronic Distribution Mechanism to anyone to whom you made an
+     Executable version available; and if made available via Electronic
+     Distribution Mechanism, must remain available for at least twelve (12)
+     months after the date it initially became available, or at least six
+     (6) months after a subsequent version of that particular Modification
+     has been made available to such recipients. You are responsible for
+     ensuring that the Source Code version remains available even if the
+     Electronic Distribution Mechanism is maintained by a third party.
+
+     3.3. Description of Modifications.
+     You must cause all Covered Code to which You contribute to contain a
+     file documenting the changes You made to create that Covered Code and
+     the date of any change. You must include a prominent statement that
+     the Modification is derived, directly or indirectly, from Original
+     Code provided by the Initial Developer and including the name of the
+     Initial Developer in (a) the Source Code, and (b) in any notice in an
+     Executable version or related documentation in which You describe the
+     origin or ownership of the Covered Code.
+
+     3.4. Intellectual Property Matters
+          (a) Third Party Claims.
+          If Contributor has knowledge that a license under a third party's
+          intellectual property rights is required to exercise the rights
+          granted by such Contributor under Sections 2.1 or 2.2,
+          Contributor must include a text file with the Source Code
+          distribution titled "LEGAL" which describes the claim and the
+          party making the claim in sufficient detail that a recipient will
+          know whom to contact. If Contributor obtains such knowledge after
+          the Modification is made available as described in Section 3.2,
+          Contributor shall promptly modify the LEGAL file in all copies
+          Contributor makes available thereafter and shall take other steps
+          (such as notifying appropriate mailing lists or newsgroups)
+          reasonably calculated to inform those who received the Covered
+          Code that new knowledge has been obtained.
+
+          (b) Contributor APIs.
+          If Contributor's Modifications include an application programming
+          interface and Contributor has knowledge of patent licenses which
+          are reasonably necessary to implement that API, Contributor must
+          also include this information in the LEGAL file.
+
+               (c)    Representations.
+          Contributor represents that, except as disclosed pursuant to
+          Section 3.4(a) above, Contributor believes that Contributor's
+          Modifications are Contributor's original creation(s) and/or
+          Contributor has sufficient rights to grant the rights conveyed by
+          this License.
+
+     3.5. Required Notices.
+     You must duplicate the notice in Exhibit A in each file of the Source
+     Code.  If it is not possible to put such notice in a particular Source
+     Code file due to its structure, then You must include such notice in a
+     location (such as a relevant directory) where a user would be likely
+     to look for such a notice.  If You created one or more Modification(s)
+     You may add your name as a Contributor to the notice described in
+     Exhibit A.  You must also duplicate this License in any documentation
+     for the Source Code where You describe recipients' rights or ownership
+     rights relating to Covered Code.  You may choose to offer, and to
+     charge a fee for, warranty, support, indemnity or liability
+     obligations to one or more recipients of Covered Code. However, You
+     may do so only on Your own behalf, and not on behalf of the Initial
+     Developer or any Contributor. You must make it absolutely clear than
+     any such warranty, support, indemnity or liability obligation is
+     offered by You alone, and You hereby agree to indemnify the Initial
+     Developer and every Contributor for any liability incurred by the
+     Initial Developer or such Contributor as a result of warranty,
+     support, indemnity or liability terms You offer.
+
+     3.6. Distribution of Executable Versions.
+     You may distribute Covered Code in Executable form only if the
+     requirements of Section 3.1-3.5 have been met for that Covered Code,
+     and if You include a notice stating that the Source Code version of
+     the Covered Code is available under the terms of this License,
+     including a description of how and where You have fulfilled the
+     obligations of Section 3.2. The notice must be conspicuously included
+     in any notice in an Executable version, related documentation or
+     collateral in which You describe recipients' rights relating to the
+     Covered Code. You may distribute the Executable version of Covered
+     Code or ownership rights under a license of Your choice, which may
+     contain terms different from this License, provided that You are in
+     compliance with the terms of this License and that the license for the
+     Executable version does not attempt to limit or alter the recipient's
+     rights in the Source Code version from the rights set forth in this
+     License. If You distribute the Executable version under a different
+     license You must make it absolutely clear that any terms which differ
+     from this License are offered by You alone, not by the Initial
+     Developer or any Contributor. You hereby agree to indemnify the
+     Initial Developer and every Contributor for any liability incurred by
+     the Initial Developer or such Contributor as a result of any such
+     terms You offer.
+
+     3.7. Larger Works.
+     You may create a Larger Work by combining Covered Code with other code
+     not governed by the terms of this License and distribute the Larger
+     Work as a single product. In such a case, You must make sure the
+     requirements of this License are fulfilled for the Covered Code.
+
+4. Inability to Comply Due to Statute or Regulation.
+
+     If it is impossible for You to comply with any of the terms of this
+     License with respect to some or all of the Covered Code due to
+     statute, judicial order, or regulation then You must: (a) comply with
+     the terms of this License to the maximum extent possible; and (b)
+     describe the limitations and the code they affect. Such description
+     must be included in the LEGAL file described in Section 3.4 and must
+     be included with all distributions of the Source Code. Except to the
+     extent prohibited by statute or regulation, such description must be
+     sufficiently detailed for a recipient of ordinary skill to be able to
+     understand it.
+
+5. Application of this License.
+
+     This License applies to code to which the Initial Developer has
+     attached the notice in Exhibit A and to related Covered Code.
+
+6. Versions of the License.
+
+     6.1. New Versions.
+     Netscape Communications Corporation ("Netscape") may publish revised
+     and/or new versions of the License from time to time. Each version
+     will be given a distinguishing version number.
+
+     6.2. Effect of New Versions.
+     Once Covered Code has been published under a particular version of the
+     License, You may always continue to use it under the terms of that
+     version. You may also choose to use such Covered Code under the terms
+     of any subsequent version of the License published by Netscape. No one
+     other than Netscape has the right to modify the terms applicable to
+     Covered Code created under this License.
+
+     6.3. Derivative Works.
+     If You create or use a modified version of this License (which you may
+     only do in order to apply it to code which is not already Covered Code
+     governed by this License), You must (a) rename Your license so that
+     the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
+     "MPL", "NPL" or any confusingly similar phrase do not appear in your
+     license (except to note that your license differs from this License)
+     and (b) otherwise make it clear that Your version of the license
+     contains terms which differ from the Mozilla Public License and
+     Netscape Public License. (Filling in the name of the Initial
+     Developer, Original Code or Contributor in the notice described in
+     Exhibit A shall not of themselves be deemed to be modifications of
+     this License.)
+
+7. DISCLAIMER OF WARRANTY.
+
+     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
+     WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
+     DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
+     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
+     IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
+     YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
+     COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
+     OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
+     ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+8. TERMINATION.
+
+     8.1.  This License and the rights granted hereunder will terminate
+     automatically if You fail to comply with terms herein and fail to cure
+     such breach within 30 days of becoming aware of the breach. All
+     sublicenses to the Covered Code which are properly granted shall
+     survive any termination of this License. Provisions which, by their
+     nature, must remain in effect beyond the termination of this License
+     shall survive.
+
+     8.2.  If You initiate litigation by asserting a patent infringement
+     claim (excluding declatory judgment actions) against Initial Developer
+     or a Contributor (the Initial Developer or Contributor against whom
+     You file such action is referred to as "Participant")  alleging that:
+
+     (a)  such Participant's Contributor Version directly or indirectly
+     infringes any patent, then any and all rights granted by such
+     Participant to You under Sections 2.1 and/or 2.2 of this License
+     shall, upon 60 days notice from Participant terminate prospectively,
+     unless if within 60 days after receipt of notice You either: (i)
+     agree in writing to pay Participant a mutually agreeable reasonable
+     royalty for Your past and future use of Modifications made by such
+     Participant, or (ii) withdraw Your litigation claim with respect to
+     the Contributor Version against such Participant.  If within 60 days
+     of notice, a reasonable royalty and payment arrangement are not
+     mutually agreed upon in writing by the parties or the litigation claim
+     is not withdrawn, the rights granted by Participant to You under
+     Sections 2.1 and/or 2.2 automatically terminate at the expiration of
+     the 60 day notice period specified above.
+
+     (b)  any software, hardware, or device, other than such Participant's
+     Contributor Version, directly or indirectly infringes any patent, then
+     any rights granted to You by such Participant under Sections 2.1(b)
+     and 2.2(b) are revoked effective as of the date You first made, used,
+     sold, distributed, or had made, Modifications made by that
+     Participant.
+
+     8.3.  If You assert a patent infringement claim against Participant
+     alleging that such Participant's Contributor Version directly or
+     indirectly infringes any patent where such claim is resolved (such as
+     by license or settlement) prior to the initiation of patent
+     infringement litigation, then the reasonable value of the licenses
+     granted by such Participant under Sections 2.1 or 2.2 shall be taken
+     into account in determining the amount or value of any payment or
+     license.
+
+     8.4.  In the event of termination under Sections 8.1 or 8.2 above,
+     all end user license agreements (excluding distributors and resellers)
+     which have been validly granted by You or any distributor hereunder
+     prior to termination shall survive termination.
+
+9. LIMITATION OF LIABILITY.
+
+     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
+     DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
+     OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
+     ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
+     CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
+     WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
+     COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN

+# About Hunspell
+
+Hunspell is a free spell checker and morphological analyzer library
+and command-line tool, licensed under LGPL/GPL/MPL tri-license.
+
+Hunspell is used by LibreOffice office suite, free browsers, like
+Mozilla Firefox and Google Chrome, and other tools and OSes, like
+Linux distributions and macOS. It is also a command-line tool for
+Linux, Unix-like and other OSes.
+
+It is designed for quick and high quality spell checking and
+correcting for languages with word-level writing system,
+including languages with rich morphology, complex word compounding
+and character encoding.
+
+Hunspell interfaces: Ispell-like terminal interface using Curses
+library, Ispell pipe interface, C++/C APIs and shared library, also
+with existing language bindings for other programming languages.
+
+Hunspell's code base comes from OpenOffice.org's MySpell library,
+developed by Kevin Hendricks (originally a C++ reimplementation of
+spell checking and affixation of Geoff Kuenning's International
+Ispell from scratch, later extended with eg. n-gram suggestions),
+see http://lingucomponent.openoffice.org/MySpell-3.zip, and
+its README, CONTRIBUTORS and license.readme (here: license.myspell) files.
+
+Main features of Hunspell library, developed by László Németh:
+
+  - Unicode support
+  - Highly customizable suggestions: word-part replacement tables and
+    stem-level phonetic and other alternative transcriptions to recognize
+    and fix all typical misspellings, don't suggest offensive words etc.
+  - Complex morphology: dictionary and affix homonyms; twofold affix
+    stripping to handle inflectional and derivational morpheme groups for
+    agglutinative languages, like Azeri, Basque, Estonian, Finnish, Hungarian,
+    Turkish; 64 thousand affix classes with arbitrary number of affixes;
+    conditional affixes, circumfixes, fogemorphemes, zero morphemes,
+    virtual dictionary stems, forbidden words to avoid overgeneration etc.
+  - Handling complex compounds (for example, for Finno-Ugric, German and
+    Indo-Aryan languages): recognizing compounds made of arbitrary
+    number of words, handle affixation within compounds etc.
+  - Custom dictionaries with affixation
+  - Stemming
+  - Morphological analysis (in custom item and arrangement style)
+  - Morphological generation
+  - SPELLML XML API over plain spell() API function for easier integration
+    of stemming, morpological generation and custom dictionaries with affixation
+  - Language specific algorithms, like special casing of Azeri or Turkish
+    dotted i and German sharp s, and special compound rules of Hungarian.
+
+Main features of Hunspell command line tool, developed by László Németh:
+
+  - Reimplementation of quick interactive interface of Geoff Kuenning's Ispell
+  - Parsing formats: text, OpenDocument, TeX/LaTeX, HTML/SGML/XML, nroff/troff
+  - Custom dictionaries with optional affixation, specified by a model word
+  - Multiple dictionary usage (for example hunspell -d en_US,de_DE,de_medical)
+  - Various filtering options (bad or good words/lines)
+  - Morphological analysis (option -m)
+  - Stemming (option -s)
+
+See man hunspell, man 3 hunspell, man 5 hunspell for complete manual.
+
+Translations: Hunspell has been translated into several languages already. If your language is missing or incomplete, please use [Weblate](https://hosted.weblate.org/engage/hunspell/) to help translate Hunspell.

+
+# Dependencies
+
+Build only dependencies:
+
+    g++ make autoconf automake autopoint libtool
+
+Runtime dependencies:
+
+|               | Mandatory        | Optional         |
+|---------------|------------------|------------------|
+|libhunspell    |                  |                  |
+|hunspell tool  | libiconv gettext | ncurses readline |
+
+# Compiling on GNU/Linux and Unixes
+
+We first need to download the dependencies. On Linux, `gettext` and
+`libiconv` are part of the standard library. On other Unixes we
+need to manually install them.
+
+For Ubuntu:
+
+    sudo apt install autoconf automake autopoint libtool
+
+Then run the following commands:
+
+    autoreconf -vfi
+    ./configure
+    make
+    sudo make install
+    sudo ldconfig
+
+For dictionary development, use the `--with-warnings` option of
+configure.
+
+For interactive user interface of Hunspell executable, use the
+`--with-ui` option.
+
+Optional developer packages:
+
+  - ncurses (need for --with-ui), eg. libncursesw5 for UTF-8
+  - readline (for fancy input line editing, configure parameter:
+    --with-readline)
+
+In Ubuntu, the packages are:
+
+    libncurses5-dev libreadline-dev
+
+# Compiling on OSX and macOS
+
+On macOS for compiler always use `clang` and not `g++` because Homebrew
+dependencies are build with that.
+
+    brew install autoconf automake libtool gettext
+    brew link gettext --force
+
+Then run:
+
+    autoreconf -vfi
+    ./configure
+    make
+
+# Compiling on Windows
+
+## Compiling with Mingw64 and MSYS2
+
+Download Msys2, update everything and install the following
+    packages:
+
+    pacman -S base-devel mingw-w64-x86_64-toolchain mingw-w64-x86_64-libtool
+
+Open Mingw-w64 Win64 prompt and compile the same way as on Linux, see
+above.
+
+## Compiling in Cygwin environment
+
+Download and install Cygwin environment for Windows with the following
+extra packages:
+
+  - make
+  - automake
+  - autoconf
+  - libtool
+  - gcc-g++ development package
+  - ncurses, readline (for user interface)
+  - iconv (character conversion)
+
+Then compile the same way as on Linux. Cygwin builds depend on
+Cygwin1.dll.
+
+# Debugging
+
+It is recommended to install a debug build of the standard library:
+
+    libstdc++6-6-dbg
+
+For debugging we need to create a debug build and then we need to start
+`gdb`.
+
+    ./configure CXXFLAGS='-g -O0 -Wall -Wextra'
+    make
+    ./libtool --mode=execute gdb src/tools/hunspell
+
+You can also pass the `CXXFLAGS` directly to `make` without calling
+`./configure`, but we don't recommend this way during long development
+sessions.
+
+If you like to develop and debug with an IDE, see documentation at
+https://github.com/hunspell/hunspell/wiki/IDE-Setup
+
+# Testing
+
+Testing Hunspell (see tests in tests/ subdirectory):
+
+    make check
+
+or with Valgrind debugger:
+
+    make check
+    VALGRIND=[Valgrind_tool] make check
+
+For example:
+
+    make check
+    VALGRIND=memcheck make check
+
+# Documentation
+
+features and dictionary format:
+
+    man 5 hunspell
+    man hunspell
+    hunspell -h
+
+http://hunspell.github.io/
+
+# Usage
+
+After compiling and installing (see INSTALL) you can run the Hunspell
+spell checker (compiled with user interface) with a Hunspell or Myspell
+dictionary:
+
+    hunspell -d en_US text.txt
+
+or without interface:
+
+    hunspell
+    hunspell -d en_GB -l <text.txt
+
+Dictionaries consist of an affix (.aff) and dictionary (.dic) file, for
+example, download American English dictionary files of LibreOffice
+(older version, but with stemming and morphological generation) with
+
+    wget -O en_US.aff  https://cgit.freedesktop.org/libreoffice/dictionaries/plain/en/en_US.aff?id=a4473e06b56bfe35187e302754f6baaa8d75e54f
+    wget -O en_US.dic https://cgit.freedesktop.org/libreoffice/dictionaries/plain/en/en_US.dic?id=a4473e06b56bfe35187e302754f6baaa8d75e54f
+
+and with command line input and output, it's possible to check its work quickly,
+for example with the input words "example", "examples", "teached" and
+"verybaaaaaaaaaaaaaaaaaaaaaad":
+
+    $ hunspell -d en_US
+    Hunspell 1.7.0
+    example
+    *
+
+    examples
+    + example
+
+    teached
+    & teached 9 0: taught, teased, reached, teaches, teacher, leached, beached
+
+    verybaaaaaaaaaaaaaaaaaaaaaad
+    # verybaaaaaaaaaaaaaaaaaaaaaad 0
+
+Where in the output, `*` and `+` mean correct (accepted) words (`*` = dictionary stem,
+`+` = affixed forms of the following dictionary stem), and
+`&` and `#` mean bad (rejected) words (`&` = with suggestions, `#` = without suggestions)
+(see man hunspell).
+
+Example for stemming:
+
+    $ hunspell -d en_US -s
+    mice
+    mice mouse
+
+Example for morphological analysis (very limited with this English dictionary):
+
+    $ hunspell -d en_US -m
+    mice
+    mice  st:mouse ts:Ns
+
+    cats
+    cats  st:cat ts:0 is:Ns
+    cats  st:cat ts:0 is:Vs
+
+# Other executables
+
+The src/tools directory contains the following executables after compiling.
+
+  - The main executable:
+      - hunspell: main program for spell checking and others (see
+        manual)
+  - Example tools:
+      - analyze: example of spell checking, stemming and morphological
+        analysis
+      - chmorph: example of automatic morphological generation and
+        conversion
+      - example: example of spell checking and suggestion
+  - Tools for dictionary development:
+      - affixcompress: dictionary generation from large (millions of
+        words) vocabularies
+      - makealias: alias compression (Hunspell only, not back compatible
+        with MySpell)
+      - wordforms: word generation (Hunspell version of unmunch)
+      - hunzip: decompressor of hzip format
+      - hzip: compressor of hzip format
+      - munch (DEPRECATED, use affixcompress): dictionary generation
+        from vocabularies (it needs an affix file, too).
+      - unmunch (DEPRECATED, use wordforms): list all recognized words
+        of a MySpell dictionary
+
+Example for morphological generation:
+
+    $ ~/hunspell/src/tools/analyze en_US.aff en_US.dic /dev/stdin
+    cat mice
+    generate(cat, mice) = cats
+    mouse cats
+    generate(mouse, cats) = mice
+    generate(mouse, cats) = mouses
+

+
+Appendix:  Understanding Affix Code
+
+
+An affix is either a  prefix or a suffix attached to root words to make 
+other words.
+
+Basically a Prefix or a Suffix is set of AffEntry objects
+which store information about the prefix or suffix along 
+with supporting routines to check if a word has a particular 
+prefix or suffix or a combination.
+
+The structure affentry is defined as follows:
+
+struct affentry
+{
+   unsigned short aflag;    // ID used to represent the affix
+   std::string strip;       // string to strip before adding affix
+   std::string appnd;       // the affix string to add
+   char numconds;           // the number of conditions that must be met
+   char opts;               // flag: aeXPRODUCT- combine both prefix and suffix 
+   char   conds[SETSIZE];   // array which encodes the conditions to be met
+};
+
+
+Here is a suffix borrowed from the en_US.aff file.  This file 
+is whitespace delimited.
+
+SFX D Y 4 
+SFX D   0     e          d
+SFX D   y     ied        [^aeiou]y
+SFX D   0     ed         [^ey]
+SFX D   0     ed         [aeiou]y
+
+This information can be interpreted as follows:
+
+In the first line has 4 fields
+
+Field
+-----
+1     SFX - indicates this is a suffix
+2     D   - is the name of the character flag which represents this suffix
+3     Y   - indicates it can be combined with prefixes (cross product)
+4     4   - indicates that sequence of 4 affentry structures are needed to
+               properly store the affix information
+
+The remaining lines describe the unique information for the 4 SfxEntry 
+objects that make up this affix.  Each line can be interpreted
+as follows: (note fields 1 and 2 are as a check against line 1 info)
+
+Field
+-----
+1     SFX         - indicates this is a suffix
+2     D           - is the name of the character flag for this affix
+3     y           - the string of chars to strip off before adding affix
+                         (a 0 here indicates the NULL string)
+4     ied         - the string of affix characters to add
+5     [^aeiou]y   - the conditions which must be met before the affix
+                    can be applied
+
+Field 5 is interesting.  Since this is a suffix, field 5 tells us that
+there are 2 conditions that must be met.  The first condition is that 
+the next to the last character in the word must *NOT* be any of the 
+following "a", "e", "i", "o" or "u".  The second condition is that
+the last character of the word must end in "y".
+
+So how can we encode this information concisely and be able to 
+test for both conditions in a fast manner?  The answer is found
+but studying the wonderful ispell code of Geoff Kuenning, et.al. 
+(now available under a normal BSD license).
+
+If we set up a conds array of 256 bytes indexed (0 to 255) and access it
+using a character (cast to an unsigned char) of a string, we have 8 bits
+of information we can store about that character.  Specifically we
+could use each bit to say if that character is allowed in any of the 
+last (or first for prefixes) 8 characters of the word.
+
+Basically, each character at one end of the word (up to the number 
+of conditions) is used to index into the conds array and the resulting 
+value found there says whether the that character is valid for a 
+specific character position in the word.  
+
+For prefixes, it does this by setting bit 0 if that char is valid 
+in the first position, bit 1 if valid in the second position, and so on. 
+
+If a bit is not set, then that char is not valid for that postion in the
+word.
+
+If working with suffixes bit 0 is used for the character closest 
+to the front, bit 1 for the next character towards the end, ..., 
+with bit numconds-1 representing the last char at the end of the string. 
+
+Note: since entries in the conds[] are 8 bits, only 8 conditions 
+(read that only 8 character positions) can be examined at one
+end of a word (the beginning for prefixes and the end for suffixes.
+
+So to make this clearer, lets encode the conds array values for the 
+first two affentries for the suffix D described earlier.
+
+
+  For the first affentry:    
+     numconds = 1             (only examine the last character)
+
+     conds['e'] =  (1 << 0)   (the word must end in an E)
+     all others are all 0
+
+  For the second affentry:
+     numconds = 2             (only examine the last two characters)     
+
+     conds[X] = conds[X] | (1 << 0)     (aeiou are not allowed)
+         where X is all characters *but* a, e, i, o, or u
+         
+
+     conds['y'] = (1 << 1)     (the last char must be a y)
+     all other bits for all other entries in the conds array are zero

+#   Changelog:
+#
+#   2000-01-05  Björn Jacke <bjoern.jacke@gmx.de>
+#               - first version with translation rules derived from
+#                 metaphone.cc distributed with aspell 0.28.3
+#               - "TH" is now representated as "@" because "0" is a
+#                 meta character
+#               - removed TH(!vowel) --> T; always use TH --> # instead
+#               - dropped "^AE" -> "E" (redundant)
+#               - "ing" is transformed to "N", not "NK"
+#               - "SCH(EO)" transforms to "SK" now
+#               - added R --> SILENT if (after a vowel) and no (vowel or
+#                 "y" follows) like in "Marcy" or "abort"
+#               - H is SILENT in RH at beginning of words
+#               - H is SILENT if vowel leads and "Y" follows
+#               - some ".OUGH.."  --> ...F exceptions added
+#               - "^V" transforms to "W"
+#   2000-01-07  Kevin Atkinson <kevinatk@home.com>
+#               Converted from header to data file.
+#
+#   2007-08-23  László Németh <nemeth AT OOo>
+#               Add PHONE header and PHONE keywords
