+Description
+This file contain the necessary and supplementary data  for typesetting documents in Italiana with babel as the manager of the language management.
+It defines the infix words, the date in various formats. Optionally lets the user activate a number of shorthands to performe routine frequent tasks by means of the active character " that can be freely activated and deactivated. It defines an intelligent mathematical comma that recognises if it has to perform as a punctuation mark or as a decimal separator. Another user command activates or deactivates some commands to supply a minimum of performance that is fully provided by the siunitx package. The file allows using babel also when a document is typeset with XeLaTeX or LuaLaTeX, even if, according to the author, polyglossia is preferred when typesetting documents in Italian, even if the gloss-italian.ldf  for polyglossia provides less facilities than the ones available with babel.
+
+The documentation that is provided by running LaTeX on the italian.dtx file provides full documentation of every facility provided by the italian.ldf file.
