/*
 *	Filename:	gmbi.c	get mailbox info
 *
 * This program will simply grab and dump the "info" fields
 * from the mailbox to display.
 *
 *  A regular expression <regex> is used to specify which of the
 *  mailboxes to grab and display.  Note that from the command line
 *  prompt the <regex> expression should be enclosed within 'single'
 *  quotes so that your shell does not try to process it...
 *
 *  Example:  gmbi 'ra+ts'
 *  Will match any ( rat ) entry that contains at least one a:
 *			ie ) rats - raats - raaats - etc...
 *
 *  Both the unqualified  gmbi  as well as  gmbi '*'   
 *  will return all mailbox entries.
 *
 *
 *  usage: gmbi <regex>
 *
 *  files used:  gmbi.c taskf.c
