Hello Uwe Bonnes,

Thanx for taking the time to download, execute and comment on Navigation
Made Easy. 

I guess the next step is to go ahead and partition my drive and install
one of the Linux's then Wine. I have Mandrake 6.5 purchased with
documentation. I have Mandrake 8.0 Beta 2 on CDs without printed
documentation. Is there a particular brand of Linux or Wine that you

The reason for Windows 3.1 right now is that my laptop is an 80486 50MHz
with 350MB drive, 20MB RAM, 1.44MB diskette, no CD drive. My desktop is
a Pentium with CD and several GB of disk. But it is the laptop on the
boat. And I do want to make changes and compile while on the boat. If I
cannot compile and run on my 486 please tell me now. I will eventually
get a newer 32 bit laptop but not this month. Nothing leftover after

Where do I find out how to bundle my stuff with the appropriate Linux
policy info?

Again, thanx for your time.
