ExtUtils::Install - install files from here to there


use ExtUtils::Install;





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.

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.

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 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.

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.
