This target allows you to have git installed in one location,

and have symbolic links to all of the programs installed in

another	location.  For example, if git was installed to /opt/git

with
	make prefix=/opt/git install
you can install symbolic links in /usr/local/bin with
	make symlinkprefix=/usr/local prefix=/opt/git \

		install-symlinks
This makes it reasonably easy to remove such a package, by doing
	rm -rf /opt/git
and then removing stale links with
	find /usr/local -xtype l -print0|xargs -0 rm
(be sure to first see whether you indeed get only stale links listed).
This works by copying the directory hierarchy of $prefix to

$symlinkprefix (not copying or descending to any directories of the

name git* matched case-insensitively), then linking all the rest.

Some people might prefer to be able to specify the find utility to

use, in particular for the more complicated usage in the

install-symlinks target.
