|

use ExtUtils::Install; |

=head1 DESCRIPTION |
| 42 |
|
| 43 |
Handles the installing and uninstalling of perl modules, scripts, man |
| 44 |
pages, etc... |
| 45 |
|
| 46 |
Both install() and uninstall() are specific to the way |
| 47 |
ExtUtils::MakeMaker handles the installation and deinstallation of |
| 48 |
perl modules. They are not designed as general purpose tools. |

install(\%from_to); |
| 57 |
install(\%from_to, $verbose, $dont_execute, $uninstall_shadows); |
| 58 |
|
| 59 |
Copies each directory tree of %from_to to its corresponding value |
| 60 |
preserving timestamps and permissions. |
| 61 |
|
| 62 |
There are two keys with a special meaning in the hash: "read" and |
| 63 |
"write". These contain packlist files. After the copying is done, |
| 64 |
install() will write the list of target files to $from_to{write}. If |
| 65 |
$from_to{read} is given the contents of this file will be merged into |
| 66 |
the written file. The read and the written file may be identical, but |
| 67 |
on AFS it is quite likely that people are installing to a different |
| 68 |
directory than the one where the files later appear. |
| 69 |
|
| 70 |
If $verbose is true, will print out each file removed. Default is |
| 71 |
false. This is "make install VERBINST=1" |
| 72 |
|
| 73 |
If $dont_execute is true it will only print what it was going to do |
| 74 |
without actually doing it. Default is false. |
| 75 |
|
| 76 |
If $uninstall_shadows is true any differing versions throughout @INC |
| 77 |
will be uninstalled. This is "make install UNINST=1" |

Calls install() with arguments to copy a module from blib/ to the |

default site installation location. |
| 258 |
|
| 259 |
$fullext is the name of the module converted to a directory |

(ie. Foo::Bar would be Foo/Bar). If $fullext is not specified, it |

will attempt to read it from @ARGV. |
| 262 |

This is primarily useful for install scripts. |

B<NOTE> This function is not really useful because of the hard-coded |
| 266 |
install location with no way to control site vs core vs vendor |
| 267 |
directories and the strange way in which the module name is given. |
| 268 |
Consider its use discouraged. |

From 1.0307 back, AutoSplit will sometimes leave an open filehandle to |
| 478 |
the file being split. This causes problems on systems with mandatory |
| 479 |
locking (ie. Windows). So we wrap it and close the filehandle. |
