# xgettext_werror.sh: Run xgettext and actually do something with the warnings

#

# xgettext prints out warnings for certain problems in translatable strings,

# such as format strings that cannot be translated due to position-based

# parameters. These warnings generally indicate something that needs to be

# addressed before the strings can be submitted for translation. This script

# exits with a status of 1 so that the warnings are not ignored as they scroll

# by in pages of build output.

#

# This script should be used in place of xgettext when rebuilding the .pot file,

# e.g. by setting XGETTEXT in po/Makevars.
