identical, but on AFS it is quite likely, people are installing to a
different directory than the one where the files later appear.
+install_default() takes one or less arguments. If no arguments are
+specified, it takes $ARGV[0] as if it was specified as an argument.
+The argument is the value of MakeMaker's C<FULLEXT> key, like F<Tk/Canvas>.
+This function calls install() with the same arguments as the defaults
+the MakeMaker would use.
+
+The argumement-less form is convenient for install scripts like
+
+ perl -MExtUtils::Install -e install_default Tk/Canvas
+
+Assuming this command is executed in a directory with populated F<blib>
+directory, it will proceed as if the F<blib> was build by MakeMaker on
+this machine. This is useful for binary distributions.
+
uninstall() takes as first argument a file containing filenames to be
unlinked. The second argument is a verbose switch, the third is a
no-don't-really-do-it-now switch.
