For instance this sentence: "Some software packages allow you to specify,
at compile-time, separate locations for installation and for run-time".
It is stow which allows to have separate locations for installation and run
time, not the package.
When I do:
cd /usr/local/stow && stow package
I have specified the location of the package at compile time, and stows
allows to run this package in a different location (/usr/local/stow/package
Another thing I don't understand is the GNU Emacs example.
The documentation mention the "new" prefix, but never the old prefix. So I
don't know which is the value of the old prefix, and which is the value of
the new prefix.
Finally, I don't understand how is it related to this thread.
