#!/bin/sh
#
# loc   Find a class or package
#
# Usage:  loc [-l] class-pattern [dirname]

#    -l    Use system locate command instead of find.  In that case, loc
#          will ignore any directory to be searched.

# Example:
#
#     $ loc -l org.objectweb.jonas.common.JProp
#     /var/lib/jonas/demoserver/ejbjars/autoload/mejb.jar
#     /var/lib/jonas/lib/common/ow_jonas_bootstrap.jar
#     /var/lib/jonas/eclipseserver/ejbjars/autoload/mejb.jar
#     /var/lib/jonas/ejbjars/autoload/mejb.jar
#     /var/cache/jonas/work/ejbjars/jonas/mejb_2005.09.15-17.01.52.jar
#     /usr/src/redhat/BUILD/jonas-4.3.3/jonas/classes/common/org/objectweb/jonas/common/JProp.class
