How to get soul into file?

[jeffmcfadden]

None of the examples explain how to get your soul into the computer so you can put it into the horcrux.

It's also unclear from the readme as to whether a murder is required.

I can confirm: murder is required

[tony-sol]

I believe, that

cat ~/.ssh/id_* > ~/.soul
horcrux split ~/.soul

is quite close to "my computer soul" ;)
