+
+Copies each directory tree of %from_to to its corresponding value
+preserving timestamps and permissions.
+
+There are two keys with a special meaning in the hash: "read" and
+"write". These contain packlist files. After the copying is done,
+install() will write the list of target files to $from_to{write}. If
+$from_to{read} is given 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 that people are installing to a different
+directory than the one where the files later appear.
+
+If $verbose is true, will print out each file removed. Default is
+false. This is "make install VERBINST=1"
+
+If $dont_execute is true it will only print what it was going to do
+without actually doing it. Default is false.
+
+If $uninstall_shadows is true any differing versions throughout @INC
+will be uninstalled. This is "make install UNINST=1"

-=head1 DESCRIPTION
+Currently maintained by Michael G Schwern <F<schwern@pobox.com>>
-Both install() and uninstall() are specific to the way
-ExtUtils::MakeMaker handles the installation and deinstallation of
-perl modules. They are not designed as general purpose tools.
+Send patches and ideas to <F<makemaker@perl.org>>.
-install() takes three arguments. A reference to a hash, a verbose
-switch and a don't-really-do-it switch. The hash ref contains a
-mapping of directories: each key/value pair is a combination of
-directories to be copied. Key is a directory to copy from, value is a
-directory to copy to. The whole tree below the "from" directory will
-be copied preserving timestamps and permissions.
+Send bug reports via http://rt.cpan.org/. Please send your
+generated Makefile along with your report.
-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 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 that 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 argument-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 a 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.
-
-pm_to_blib() takes a hashref as the first argument and copies all keys
-of the hash to the corresponding values efficiently. Filenames with
-the extension pm are autosplit. Second argument is the autosplit
-directory. If third argument is not empty, it is taken as a filter command
-to be ran on each .pm file, the output of the command being what is finally
-copied, and the source for auto-splitting.
