Subject: [PATCH] Add support for eSpeak-NG
It is mostly a copy of the eSpeak driver.
Squashed with Dave Mielke's commit:
Some modifications to the introduction of the eSpeak-NG speech driver: (dm)
Fix the order of lists that are alphabetically sorted by driver code.
Undo the changes to the derived Portuguese documents.

+This directory contains the BRLTTY speech driver for the eSpeak-NG text to
+speech engine. The eSpeak-NG web site is
+https://github.com/espeak-ng/espeak-ng/.
+
+eSpeak-NG comes with a simple command-line tool called espeak-ng which can be
+used to test it, and to recompile modified dictionaries, etc. Please see
+the espeak-ng man page for more information.
+
+BRLTTY's configure script automatically includes this driver if the
+eSpeak-NG development library is installed.
+
+This driver recognizes the following parameters:
+
+path
+
+ Specifies the directory containing the espeak-ng-data directory.
+ If not specified, the default location is used.
+
+punctlist
+
+ Specified a list of punctuation characters whose names are to be
+ spoken when the speech punctuation parameter is set to "Some".
+ If not specified, a default list is used.
+
+voice
+
+ Specifies a voice/language to use. The complete list of available
+ voices may be obtained with the command 'espeak-ng --voices'.
+
+maxrate
+
+ Overrides the maximum speech rate value. The default is 450.
+ This cannot be lower than 80.
