+** List of all hash files (languages) which will be supported by ispell.
+**
+** This variable has a complex format so that many options can be
+** specified.  The format is as follows:
+**
+**	<language>[,<make-options>...] [<language> [,<make-options> ...] ...]
+**
+** where
+**
+**	language	is the name of a subdirectory of the
+**			"languages" directory
+**	make-options	are options that are to be passed to "make" in
+**			the specified directory.  The make-options
+**			should not, in general, specify a target, as
+**			this will be provided by the make process.
+**
+** For example, if LANGUAGES is:
+**
+**	"{american,MASTERDICTS=american.med+,HASHFILES=americanmed+.hash,EXTRADICT=/usr/dict/words /usr/dict/web2} {deutsch,DICTALWAYS=deutsch.sml,DICTOPTIONS=}"
+**
+** then the American-English and Deutsch (German) languages will be supported,
+** and the following variable settings will be passed to the two Makefiles:
+**
+**	American:
+**
+**	    MASTERDICTS='american.med+'
+**	    HASHFILES='americanmed+.hash'
+**	    EXTRADICT='/usr/dict/words /usr/dict/web2'
+**
+**	Deutsch:
+**
+**	    DICTALWAYS='deutsch.sml'
+**	    DICTOPTIONS=''
+**
+** Notes on the syntax: The makefile is not very robust.  If you have
+** make problems, or if make seems to fail in the language-subdirs
+** dependency, check your syntax.  The makefile adds single quotes to
+** the individual variables in the LANGUAGES specification, so don't
+** use quotes of any kind.
+**
+** In the future, the first language listed in this variable will
+** become the default, and the DEFHASH, DEFLANG, and DEFPAFF,
+** variables will all become obsolete.  So be sure to put your default
+** language first, to make later conversion easier!
+**
+** Notes on options for the various languages will be found in the
+** Makefiles for those languages.  Some of those languages may require
+** you to also change various limits limits like MASKBITS or the
+** length parameters.
+**
+** A special note on the English language: because the British and
+** American dialects use different spelling, you should usually select
+** one or the other of these.  If you select both, the setting of
+** MASTERHASH will determine which becomes the language linked to
+** DEFHASH (which will usually be named english.hash).
+**
+** On MSDOS systems you must use names which are consistent with the

+ * $Log$
+ * Revision 1.68  1995/03/06  02:42:41  geoff
+ * Be vastly more paranoid about parenthesizing macro arguments.  This
+ * fixes a bug in defmt.c where a complex argument was passed to
+ * isstringch.
+ *
+ * Revision 1.67  1995/01/03  19:24:12  geoff
+ * Get rid of a non-global declaration.
+ *
+ * Revision 1.66  1994/12/27  23:08:49  geoff
+ * Fix a lot of subtly bad assumptions about the widths of ints and longs
+ * which only show up on 64-bit machines like the Cray and the DEC Alpha.
+ *
+ * Revision 1.65  1994/11/02  06:56:10  geoff
+ * Remove the anyword feature, which I've decided is a bad idea.
+ *
+ * Revision 1.64  1994/10/25  05:46:18  geoff
+ * Add the FF_ANYWORD flag for defining an affix that will apply to any
+ * word, even if not explicitly specified.  (Good for French.)
+ *
+ * Revision 1.63  1994/09/16  04:48:28  geoff
+ * Make stringdups and laststringch unsigned ints, and dupnos a plain
+ * int, so that we can handle more than 128 stringchars and stringchar
+ * types.
+ *
+ * Revision 1.62  1994/09/01  06:06:39  geoff
+ * Change erasechar/killchar to uerasechar/ukillchar to avoid
+ * shared-library problems on HP systems.
+ *
+ * Revision 1.61  1994/08/31  05:58:35  geoff
+ * Add contextoffset, used in -a mode to handle extremely long lines.
+ *
+ * Revision 1.60  1994/05/17  06:44:15  geoff
+ * Add support for controlled compound formation and the COMPOUNDONLY
+ * option to affix flags.
+ *
+ * Revision 1.59  1994/03/15  06:25:16  geoff
+ * Change deftflag's initialization so we can tell if -t/-n appeared.
+ *
+ * Revision 1.58  1994/02/07  05:53:28  geoff
+ * Add typecasts to the the 7-bit versions of ichar* routines
+ *
+ * Revision 1.57  1994/01/25  07:11:48  geoff
+ * Get rid of all old RCS log lines in preparation for the 3.1 release.

+**
+** If a word has only one capitalization form, and that form is not
+** FOLLOWCASE, it will have exactly one entry in the dictionary.  The
+** legal capitalizations will be indicated by the 2-bit capitalization
+** field, as follows:
+**
+**	ALLCAPS		The word must appear in all capitals.
+**	CAPITALIZED	The word must be capitalized (e.g., London).
+**			It will also be accepted in all capitals.
+**	ANYCASE		The word may appear in lowercase, capitalized,
+**			or all-capitals.
+**
+** Regardless of the capitalization flags, the "word" field of the entry
+** will point to an all-uppercase copy of the word.  This is to simplify
+** the large portion of the code that doesn't care about capitalization.
+** Ispell will generate the correct version when needed.
+**
+** If a word has more than one capitalization, there will be multiple
+** entries for it, linked together by the "next" field.  The initial
+** entry for such words will be a dummy entry, primarily for use by code
+** that ignores capitalization.  The "word" field of this entry will
+** again point to an all-uppercase copy of the word.  The "mask" field
+** will contain the logical OR of the mask fields of all variants.
+** A header entry is indicated by a capitalization type of ALLCAPS,
+** with the MOREVARIANTS bit set.
+**
+** The following entries will define the individual variants.  Each
+** entry except the last has the MOREVARIANTS flag set, and each
+** contains one of the following capitalization options:
+**
+**	ALLCAPS		The word must appear in all capitals.
+**	CAPITALIZED	The word must be capitalized (e.g., London).
+**			It will also be accepted in all capitals.
+**	FOLLOWCASE	The word must be capitalized exactly like the
+**			sample in the entry.  Prefix (suffix) characters
+**			must be rendered in the case of the first (last)
+**			"alphabetic" character.  It will also be accepted
+**			in all capitals.  ("Alphabetic" means "mentioned
+**			in a 'casechars' statement".)
+**	ANYCASE		The word may appear in lowercase, capitalized,
+**			or all-capitals.
+**
+** The "mask" field for the entry contains only the affix flag bits that
+** are legal for that capitalization.  The "word" field will be null
+** except for FOLLOWCASE entries, where it will point to the
+** correctly-capitalized spelling of the root word.
+**
+** It is worth discussing why the ALLCAPS option is used in
+** the header entry.  The header entry accepts an all-capitals
+** version of the root plus every affix (this is always legal, since
+** words get capitalized in headers and so forth).  Further, all of
+** the following variant entries will reject any all-capitals form
+** that is illegal due to an affix.
+**
+** Finally, note that variations in the KEEP flag can cause a multiple-variant
+** entry as well.  For example, if the personal dictionary contains "ALPHA",
+** (KEEP flag set) and the user adds "alpha" with the KEEP flag clear, a
+** multiple-variant entry will be created so that "alpha" will be accepted
+** but only "ALPHA" will actually be kept.

+** List of all hash files (languages) which will be supported by ispell.
+**
+** This variable has a complex format so that many options can be
+** specified.  The format is as follows:
+**
+**	<language>[,<make-options>...] [<language> [,<make-options> ...] ...]
+**
+** where
+**
+**	language	is the name of a subdirectory of the
+**			"languages" directory
+**	make-options	are options that are to be passed to "make" in
+**			the specified directory.  The make-options
+**			should not, in general, specify a target, as
+**			this will be provided by the make process.
+**
+** For example, if LANGUAGES is:
+**
+**	"{american,EXTRADICT=/usr/dict/words /usr/dict/web2} {deutsch}",
+**
+** then the American-English and Deutsch (German) languages will be supported,
+** and when the English dictionary is built, the variable
+** 'EXTRADICT=/usr/dict/words /usr/dict/web2' will be passed to the makefile.
+**
+** Notes on the syntax: The makefile is not very robust.  If you have
+** make problems, or if make seems to in the language-subdirs
+** dependency, check your syntax.  The makefile adds single quotes to
+** the individual variables in the LANGUAGES specification, so don't
+** use quotes of any kind.
+**
+** In the future, the first language listed in this variable will
+** become the default, and the DEFHASH, DEFLANG, and DEFPAFF,
+** variables will all become obsolete.  So be sure to put your default
+** language first, to make later conversion easier!
+**
+** Notes on options for the various languages will be found in the
+** Makefiles for those languages.  Some of those languages may require
+** you to also change various limits limits like MASKBITS or the
+** length parameters.
+**
+** A special note on the English language: because the British and
+** American dialects use different spelling, you should usually select
+** one or the other of these.  If you select both, the setting of

+** storage, and space is malloc'ed if newp is to be kept.  The newp->word
+** field must have been allocated with mymalloc, so that this routine may free
+** the space if it keeps newp but not the word.
+**
+** Return value:  0 if the word was added, 1 if the word was combined
+** with an existing entry, and -1 if trouble occurred(e.g., malloc).
+** If 1 is returned, newp->word may have been be freed using myfree.
+**
+** Life is made much more difficult by the KEEP flag's possibilities.  We
+** must ensure that a !KEEP word doesn't find its way into the personal
+** dictionary as a result of this routine's actions.  However, a !KEEP
+** word that has affixes must have come from the main dictionary, so it
+** is acceptable to combine entries in that case(got that?).
+**
+** The net result of all this is a set of rules that is a bloody pain
+** to figure out.  Basically, we want to choose one of the following actions:
+**
+**	(1) Add newp's affixes and KEEP flag to oldp, and discard newp.
+**	(2) Add oldp's affixes and KEEP flag to newp, replace oldp with
+**	    newp, and discard newp.
+#ifndef NO_CAPITALIZATION_SUPPORT
+**	(3) Insert newp as a new entry in the variants list.  If there is
+**	    currently no variant header, this requires adding one.  Adding a
+**	    header splits into two sub-cases:
+**
+**	   (3a) If oldp is ALLCAPS and the KEEP flags match, just turn it
+**		into the header.
+**	   (3b) Otherwise, add a new entry to serve as the header.
+**		To ease list linking, this is done by copying oldp into
+**		the new entry, and then performing(3a).
+**
+**	    After newp has been added as a variant, its affixes and KEEP
+**	    flag are OR-ed into the variant header.
+#endif
+**
+** So how to choose which?  The default is always case(3), which adds newp
+** as a new entry in the variants list.  Cases(1) and (2) are symmetrical
+** except for which entry is discarded.  We can use case(1) or (2) whenever
+** one entry "covers" the other.  "Covering" is defined as follows:
+**
+**	(4) For entries with matching capitalization types, A covers B
+**	    if:
+**
+**	   (4a) B's affix flags are a subset of A's, or the KEEP flags
+**		 match, and
+**	   (4b) either the KEEP flags match, or A's KEEP flag is set.
+**		(Since A has more suffixes, combining B with it won't
+**		cause any extra suffixes to be added to the dictionary.)
+**	   (4c) If the words are FOLLOWCASE, the capitalizations match
+**		exactly.
+**
+#ifndef NO_CAPITALIZATION_SUPPORT
+**	(5) For entries with mismatched capitalization types, A covers B
+**	    if(4a) and(4b) are true, and:
+**
+**	   (5a) B is ALLCAPS, or
+**	   (5b) A is ANYCASE, and B is CAPITALIZED.

+ * Revision 1.31  1994/10/25  05:46:25  geoff

+ * Revision 1.30  1994/05/24  06:23:08  geoff
+ * Don't create a hit if "allhits" is clear and capitalization

+ * and yet not found.
+ *
+ * Revision 1.29  1994/05/17  06:44:21  geoff
+ * Add support for controlled compound formation and the COMPOUNDONLY
+ * option to affix flags.
+ *
+ * Revision 1.28  1994/01/25  07:12:13  geoff
+ * Get rid of all old RCS log lines in preparation for the 3.1 release.
