smarty-gettext 1.2.0-1ubuntu1 (arm64 binary) in ubuntu xenial

 Smarty Gettext is a Smarty plugin providing internationalization support
 based on the standard gettext mechanism. Smarty is a popular PHP templating
 engine.
 .
 You need the PHP command line interpreter if you wish to use the tsmarty2c
 program: it lets you extract localizable strings from a Smarty template so
 that you can use the normal gettext tools afterwards.
