[ILUG] [TOTD] querying the locale database

On Thu, Sep 30, 2004 at 12:50:59PM +0100 or so it is rumoured hereabouts, 
P at draigBrady.com thought:

Thanks Padraig!

I've scripted that up just for fun.  Here it is.  Call it what you wish,
I've called it 'loc'

useage() {
cat << USE

Useage:	$0 <country> [<field>] | <country_code> [<field>] | country 
	$0 -? [<lc_type>] | -h

	Display locale information for the designated country.

	In the first format, '`basename $0`' displays information from the 
	locale database for the specified country, country_code or lists
	the countries in the database.  All arguments are used as regexps.
	The first argument to the command is interpreted as follows:

	The word "country" causes the listing of countries. 
	An underscore '_' in the word is interpreted as a country_code
	Otherwise it is interpreted as a country name.

	In the second format, the available lc_types are displayed or, if
	a particular lc_type is specified, the fields for that lc_type are
	displayed.

Options:
	-?	Display the possible lc_types or fields

	-h	Display this help message
