# @FUNCTION: strip-linguas
|
|
# @USAGE: [<allow LINGUAS>|<-i|-u> <directories of .po files>]
|
|
# @DESCRIPTION:
|
|
# Make sure that LINGUAS only contains languages that a package can
|
|
# support. The first form allows you to specify a list of LINGUAS.
|
|
# The -i builds a list of po files found in all the directories and uses
|
|
# the intersection of the lists. The -u builds a list of po files found
|
|
# in all the directories and uses the union of the lists.
