[commit text mostly pinched from INSTALL]
An alternative global installation method making it much easier to
uninstall is to use a package-specific prefix like /opt/git, then
create symlinks from /usr/local into that hierarchy. Uninstalling can
then be achieved by
# rm -rf /opt/git; find /usr/local -xtype l -delete
You can create a setup like that after having used one of the above
install recipes with prefix=/opt/git by writing
# make prefix=/opt/git symlinkprefix=/usr/local install-symlinks
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.
