@section Getting the list of supported languages
The naming convention for the languages follows the @cite{ISO 639-1} standard,
for which you can find a summary list in the
@uref{https://www.gnu.org/software/gettext/manual/html_node/Usual-Language-Codes.html, GNU gettext manual}.
But as @sc{Window Maker} does not support all of them, the @command{configure} script will print a
warning for each language you specify that it does not know, and sum up at the end the list of
enabled languages that will be installed.
There is a non-standard possibility to set @env{LINGUAS} to @code{list}, in which case the
@command{configure} script will provide you the list of languages it supports, and stop:
@example
./configure LINGUAS="list"
@end example
There is also another non-standard possibility to enable all the languages that @sc{Window Maker}
supports by setting @env{LINGUAS} to @code{*}.
This is an internal trick implemented so the development team can have the command
@command{make distcheck} include some checks on translations:
@example
./configure LINGUAS='*'
@end example
