# Extract getxt strings from source and generate an array for usage in
# the script using our getxt function.

# USAGE: getxt-gen-l10n-array.sh SRC ARRAYNAME ARRAYFILE
#
#        Where SRC is the shell script using getxt and ARRAYFILE is
#        the file to which the generated array is to be saved.
#
#        ARRAYNAME is the name of the associative bash array to generate.
#
#        If ARRAYFILE exists, values already defined will be preserved,
#        if the MSGID still exists.

# NOTE: we can't handle quoted quotes: "\"" -- don't use them for
#        now...
