** 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).
