To re-verify the integrity and (potentially) re-download previously removed/corrupted distfiles for all currently installed packages, run:

emerge --ask --fetchonly --emptytree @world  

 

 

localization 


L10N="en_US"
LINGUAS="en_US"    

 

LINGUAS="", most ebuilds would install only the packages' default language but none of the LC_MESSAGES files.  

A USE_EXPAND variable called L10N decides which extra localization support will be installed.

complex entries have a different syntax because L10N uses IETF language tags (aka BCP 47). For example, pt_BR and sr@latin in LINGUAS become pt-BR and sr-Latn in L10N, respectively.
