#this script has been created to translate English <-> Non-English certain files that are related to the desktop in some way.
#the files to be translated, and the translations, are defined in /usr/share/sss/desk_strings/
#note, the translations in /usr/share/sss are managed by MoManager (see Utility menu).
#fixdesk has to be called whenever the locale is changed.
#note, the SSS domain 'menu_strings' (/usr/share/sss/menu_strings) is read by /usr/sbin/fixmenus.
#120209 first release.
#120209 this script now called from /usr/sbin/quicksetup, whenever locale is changed.
#120209 convert this script into generic handler of sss-domains, allow symlinks (ex: fixscripts now a symlink to fixdesk).
#120211 major overhaul to ensure integrity of translation of target files back to en.
#120212 bugfix.
#120216 major rewrite, sss translation file now uses simple sed expressions.
#121124 ensure that all [ ] are escaped. see also /usr/sbin/fixmenus, lang2initrd.
#121125 revert 121124.
#121126 restore 121124, plus escape '.' chars in regex.

#Note to developers:
#you can run "fixdesk en" or "fixdesk de" in a terminal to convert the target files to en or de
#(or other language). this is convenient for testing your translations.
