ripxplore updated

[Jonno Downes <jonnosan@gmail.com>]

I've just released version 0.7.2 of ripxplore (a command line tool and
supporting ruby library for exploring disk images for Apple 2, C64,
TRS-80, et al).

The major change was to incorporate the create/update/delete features
from my previous 'dsktool' project. This means Apple DOS and Apple CPM
file systems can be initialised and files added or removed from it.
I've also added the ability to create a blank 'Beautiful Boot' dsk
image. As an example of how and why this is done, here's an excerpt
from the Makefile used to build a dsk with differest test apps on it
I'm using to test different parts of the netboot65 code:

ip65test.dsk: testdns.pg2 testdottedquad.pg2
		ripxplore.rb --init BeautifulBoot ip65test.dsk -a testdns.pg2 -t
AppleBinary
		ripxplore.rb ip65test.dsk -a testdottedquad.pg2 -t AppleBinary

If you've installed a previous version of ripxplore, you can update to
0.7.2 by typing 'gem update ripxplore' at a command prompt.

If you want to install ripxplore for the first time, you will first
need to install ruby ( http://www.ruby-lang.org/en/downloads/ ) - then
once ruby is installed correctly, type 'gem install ripxplore' at a
command prompt.

NB - it can take up to a day for a ruby gem to propogate to all the
mirrors, so if you end up with the prior version of ripxplore (0.5.2)
you will need to wait a few hours then do a 'gem update ripxplore'
