CEG - Currency Exchange Grabber
 
=head1 SYNOPSIS
 
    perl ceg.pl 50 USD JPY
 
=head1 DESCRIPTION
 
    Here is a rough break-down of what each of the ARGV's are needed, 
+and mean:
    perl ceg.pl ($amount) ($cf - convert from) ($ct - convert to)

    This progam's use and reason for being created, is simply for anyo
+ne that wants 
    to be able to check the exchange rates for different types of mone
+y, such as from 
    other countries.  Say one was going on a trip to Japan, and they l
+ive currently in 
    the United States.  They would need to find out how much money the
+y should bring, 
    in order to have a good amount, and there isn't an easier way (alm
+ost) than to just 
    enter in the amount you want converted using CEG and telling it to
+ convert from what 
    type of money, to the other country's money.

    It is a very simple program, and is really the first time I have u
+sed LWP to do 
    something (useful,) so it could have a lot of new features to add 
+in the future, and 
    possible bug fixes, or efficiency caveats that could be changed, a
+nd so on.
