From 75bd34df7acba7b20bc7981f2484e79e19032d4a Mon Sep 17 00:00:00 2001

Subject: [PATCH] Bug 8044: (follow-up) fix warning and error messages in
 translate.pl

CHARSET is now automatically replaced by UTF-8, and 'update' creates the
PO file if it does not exist.

Also do not try to create PO files if POT file creation failed (when
there is no messages to translate for example).

+ add some verbosity
+ add Locale::Maketext and Locale::Maketext::Lexicon to Koha
dependencies
