54+
--------------
55+
56+
This binary distribution contains the below components. Components listed under
57+
the "required" section must be redistributed with all applications using CEF.
58+
Components listed under the "optional" section may be excluded if the related
59+
features will not be used.

71+
from this folder based on the value of environment variables which are read
72+
with the following precedence order: LANGUAGE, LC_ALL, LC_MESSAGES and LANG.
73+
Only configured locales need to be distributed. If no locale is configured the
74+
default locale of "en-US" will be used. Locale file loading can be disabled
75+
completely using CefSettings.pack_loading_disabled. The locales folder path
76+
can be customized using CefSettings.locales_dir_path.
