There are two keys with a special meaning in the hash: "read" and
"write". After the copying is done, install will write the list of
-target files to the file named by $hashref->{write}. If there is
-another file named by $hashref->{read}, the contents of this file will
+target files to the file named by C<$hashref-E<gt>{write}>. If there is
+another file named by C<$hashref-E<gt>{read}>, the contents of this file will
be merged into the written file. The read and the written file may be
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.
directory.
