321 B<pm_to_blib($hashref);>
325 Both install() and uninstall() are specific to the way
326 ExtUtils::MakeMaker handles the installation and deinstallation of
327 perl modules. They are not designed as general purpose tools.
329 install() takes three arguments. A reference to a hash, a verbose
330 switch and a don't-really-do-it switch. The hash ref contains a
331 mapping of directories: each key/value pair is a combination of
332 directories to be copied. Key is a directory to copy from, value is a
333 directory to copy to. The whole tree below the "from" directory will
334 be copied preserving timestamps and permissions.
336 There are two keys with a special meaning in the hash: "read" and
337 "write". After the copying is done, install will write the list of
338 target files to the file named by C<$hashref-E<gt>{write}>. If there is
339 another file named by C<$hashref-E<gt>{read}>, the contents of this file will
340 be merged into the written file. The read and the written file may be
341 identical, but on AFS it is quite likely that people are installing to a
342 different directory than the one where the files later appear.
344 install_default() takes one or less arguments. If no arguments are
345 specified, it takes $ARGV[0] as if it was specified as an argument.
346 The argument is the value of MakeMaker's C<FULLEXT> key, like F<Tk/Canvas>.
347 This function calls install() with the same arguments as the defaults
348 the MakeMaker would use.
350 The argument-less form is convenient for install scripts like
352 perl -MExtUtils::Install -e install_default Tk/Canvas
354 Assuming this command is executed in a directory with a populated F<blib>
355 directory, it will proceed as if the F<blib> was build by MakeMaker on
356 this machine. This is useful for binary distributions.
358 uninstall() takes as first argument a file containing filenames to be
359 unlinked. The second argument is a verbose switch, the third is a
360 no-don't-really-do-it-now switch.
362 pm_to_blib() takes a hashref as the first argument and copies all keys
363 of the hash to the corresponding values efficiently. Filenames with
364 the extension pm are autosplit. Second argument is the autosplit
