# script to make 'translation' for en_US from *.pot --
# not a real translation; just copy msgid to msgstr, adding
# typographical quotes, etc. -- the output is UTF-8, and
# this script contains UTF-8 in sed args
#
# this is not useful for real (non-English) translations
#
# Note that date "+%Y-%m-%d %H:%M %Z", as used below, is close
# to but not exactly the format requested in the xgettext
# generated .pot file.  The numeric time-zone offset would
# require `date "+%Y-%m-%d %H:%M%z"`, but posix lacks the
# (lowercase) '%z' spec.. See:
