Hello Bil,
I am sitting in the Internet Cafee in Strasbourg and stay there up to 19:00
Please test the new version of the script...
'xgettext' will produce 8 strings to translate:
msgid "usage: $0 [-X] [-p <user>] -c <command>\\n -c command: command to execute\\n -p <user>: user to switch to (default: root)\\n -X: command is a X11 program\\n"
msgid "About to execute $COMMAND.\\nThis command needs $PRIV privileges to be executed.\\n
msgid "Using $suname...\\nEnter $PRIV passwd:\\n"
msgid "Y"
msgid "y"
msgid "N"
msgid "n"
msgid "Incorrect password or command failed. Try again? (y/n)'"

sonce the gettext strings in a shell script are:
gettext 'Hello Bil!'
or
eval_gettext "Hellp ${FRIEND}!"
I use now at the beginning of the shell scripts:
----8>----------------------------------
if [ -n "$(which gettext)" ] ; then
. gettext.sh
TEXTDOMAIN=exampleprog
TEXTDOMAINDIR=/usr/share/locale
else
gettext()
{
echo "$1"
}
eval_gettext()
{
echo "$1"
}
fi
----8>----------------------------------
Which works without any errors...

echo "Please answer with Y or N:"

^^
Are
Unfortunatly not, but maybe we can ask the "gettext" maintainer to
add my sniplet

I will test it...
