 will install the git programs in your own ~/bin/ directory.  If you want
 to do a global install, you can do

-       # make prefix=/usr install ;# as root
+       $ make prefix=/usr all doc ;# as yourself
+       # make prefix=/usr install install-doc ;# as root
 
 (or prefix=/usr/local, of course).  Just like any program suite
 that uses $prefix, the built results have some paths encoded,
 which are derived from $prefix, so "make all; make prefix=/usr
 install" would not work.
 
+Alternatively you can use autoconf generated ./configure script to
+set up install paths (via config.mak.autogen), so you can write instead
+
+       $ autoconf ;# as yourself if ./configure doesn't exist yet
