[Bug-ddrescue] version 1.10 Speed on HFS+/OS 10.5

[John]

So I compiled version 1.10 successfully and ran gddrescue using the 
following command:
sudo ./ddrescue -v /dev/disk1s3 MyVolImage.dmg MyVolRescue.log

The drive was an 80GB 2.5 inch drive from a laptop which would not boot.

It took about 2 days and when it finished I was very pleased with the 
results.

I was running it on a 2 GHz Intel core duo with 2 GB ram and Mac OS X 10.5.8

I am curious if there isn't some way to speed things up?

I would also like to read more of the documentation so if anyone can 
enlighten me on some tutorial that tells me how to get around on the 
text reader the help is displayed with it would be very helpful. I seem 
to get into loops within the help file so I am guessing if I could find 
something on the text editor that it's displayed with I could get over 
*that* hump.

I note there is a version 1.11 now. How do I update my current version 
to 1.11? Is it as simple as downloading the newer versions and running make?

Many thanks!
John
