+@defvar fast_install
+Determines whether libtool will privilege the installer or the
+developer.  The assumption is that installers will seldom run programs
+in the build tree, and the developer will seldom install.  This is only
+meaningful on platforms in which @var{shlibpath_overrides_runpath} is
+not @samp{yes}, so @var{fast_install} will be set to @samp{needless} in
+this case.  If @var{fast_install} set to @samp{yes}, libtool will create
+programs that search for installed libraries, and, if a program is run
+in the build tree, a new copy will be linked on-demand to use the
+yet-to-be-installed libraries.  If set to @samp{no}, libtool will create
+programs that use the yet-to-be-installed libraries, and will link
+a new copy of the program at install time.  The default value is
+@samp{yes} or @samp{needless}, depending on platform and configuration
+flags, and it can be turned from @samp{yes} to @samp{no} with the
+configure flag @samp{--disable-fast-install}.
