+## projects that directly invoke the generated libtool script at   ##
+## configure time (bad practice to beging with, should never be    ##
+## necessary in the first place).                                  ##

+## By default, slibtool.sh is _NOT_ copied to a project's build    ##
+## directory. If found by configure, however (either as a symlink  ##
+## to the system installed slibtool.sh or as a physical copy of    ##
+## the above, configure shall create ``libtool'' as a symlink to   ##
+## this script.                                                    ##
