	\par Syntaxes supported, not really language codes.
	\arg \b en - English
	\arg \b de - German
	\arg \b es - Spanish
	\arg \b fr - French
	\arg \b it = Italian
	\arg \b nl - Dutch
	\arg \b pt - Polish
	\arg \b pt - Portuguese
	\arg \b pt_BR - Portuguese (Brazil)
	\arg \b gr - Greek
	\arg \b no - Norwegian
	\arg \b se - Swedish
	\arg \b ua - Ukrainian
	\arg \b he - Hebrew

German requires the following additional soundfile:
\arg \b 1F	einE (feminine)

Spanish requires the following additional soundfile:
\arg \b 1M      un (masculine)

Dutch, Portuguese & Spanish require the following additional soundfiles:
\arg \b vm-INBOXs	singular of 'new'
\arg \b vm-Olds		singular of 'old/heard/read'

NB these are plural:
\arg \b vm-INBOX	nieuwe (nl)
\arg \b vm-Old		oude (nl)

Polish uses:
\arg \b vm-new-a	'new', feminine singular accusative
\arg \b vm-new-e	'new', feminine plural accusative
\arg \b vm-new-ych	'new', feminine plural genitive
\arg \b vm-old-a	'old', feminine singular accusative
\arg \b vm-old-e	'old', feminine plural accusative
\arg \b vm-old-ych	'old', feminine plural genitive
\arg \b digits/1-a	'one', not always same as 'digits/1'
\arg \b digits/2-ie	'two', not always same as 'digits/2'

Swedish uses:
\arg \b vm-nytt		singular of 'new'
\arg \b vm-nya		plural of 'new'
\arg \b vm-gammalt	singular of 'old'
\arg \b vm-gamla	plural of 'old'
\arg \b digits/ett	'one', not always same as 'digits/1'

Norwegian uses:
\arg \b vm-ny		singular of 'new'
\arg \b vm-nye		plural of 'new'
\arg \b vm-gammel	singular of 'old'
\arg \b vm-gamle	plural of 'old'

Dutch also uses:
\arg \b nl-om		'at'?

Spanish also uses:
\arg \b vm-youhaveno

Italian requires the following additional soundfile:

For vm_intro_it:
\arg \b vm-nuovo	new
\arg \b vm-nuovi	new plural
\arg \b vm-vecchio	old
\arg \b vm-vecchi	old plural

Hebrew also uses:
\arg \b vm-INBOX1 '1 new message'
\arg \b vm-OLD1   '1 old message'
\arg \b vm-shtei	'shtei'
\arg \b vm-nomessages 'you have no new messages'

\note Don't use vm-INBOX or vm-Old, because they are the name of the INBOX and Old folders,
spelled among others when you have to change folder. For the above reasons, vm-INBOX
and vm-Old are spelled plural, to make them sound more as folder name than an adjective.

/* Version of vm_intro() designed to work for many languages.
 *
 * It is hoped that this function can prevent the proliferation of 
 * language-specific vm_intro() functions and in time replace the language-
 * specific functions which already exist.  An examination of the language-
 * specific functions revealed that they all corrected the same deficiencies
 * in vm_intro_en() (which was the default function). Namely:
 *
 *  1) The vm-Old and vm-INBOX sound files were overloaded.  The English 
 *     wording of the voicemail greeting hides this problem.  For example,
 *     vm-INBOX contains only the word "new".  This means that both of these
 *     sequences produce valid utterances:
 *      * vm-youhave digit/1 vm-INBOX vm-message (you have one new message)
 *      * vm-press digit/1 vm-for vm-INBOX vm-messages (press 1 for new messages)
 *     However, if we rerecord vm-INBOX to say "the new" (which is unavoidable
 *     in many languages) the first utterance becomes "you have 1 the new message".
 *  2) The function contains hardcoded rules for pluralizing the word "message".
 *     These rules are correct for English, but not for many other languages.
 *  3) No attempt is made to pluralize the adjectives ("old" and "new") as
 *     required in many languages.
 *  4) The gender of the word for "message" is not specified. This is a problem
 *     because in many languages the gender of the number in phrases such
 *     as "you have one new message" must match the gender of the word
 *     meaning "message".
 *
 * Fixing these problems for each new language has meant duplication of effort.
 * This new function solves the problems in the following general ways:
 *  1) Add new sound files vm-new and vm-old.  These can be linked to vm-INBOX
 *     and vm-Old respectively for those languages where it makes sense.
 *  2) Call ast_say_counted_noun() to put the proper gender and number prefix
 *     on vm-message.
 *  3) Call ast_say_counted_adjective() to put the proper gender and number
 *     prefix on vm-new and vm-old (none for English).
 *  4) Pass the gender of the language's word for "message" as an agument to
 *     this function which is can in turn pass on to the functions which 
 *     say numbers and put endings on nounds and adjectives.
 *
 * All languages require these messages:
 *  vm-youhave		"You have..."
 *  vm-and		"and"
 *  vm-no		"no" (in the sense of "none", as in "you have no messages")
 *
 * To use it for English, you will need these additional sound files:
 *  vm-new		"new"
 *  vm-message		"message", singular
 *  vm-messages		"messages", plural
 *
 * If you use it for Russian and other slavic languages, you will need these additional sound files:
 *
 *  vm-newn		"novoye" (singular, neuter)
 *  vm-newx		"novikh" (counting plural form, genative plural)
 *  vm-message		"sobsheniye" (singular form)
 *  vm-messagex1	"sobsheniya" (first counting plural form, genative singular)
 *  vm-messagex2	"sobsheniy" (second counting plural form, genative plural)
 *  digits/1n		"odno" (neuter singular for phrases such as "one message" or "thirty one messages")
 *  digits/2n		"dva" (neuter singular)
