=head1 SYNOPSIS |
55
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
In Makefile.PL: |
57
|
|
|
|
|
|
|
use inc::Module::Install; |
58
|
|
|
|
|
|
|
... |
59
|
|
|
|
|
|
|
check_custom_installation(); |

=head1 DESCRIPTION |
63
|
|
|
|
|
|
|
|
64
|
|
|
|
|
|
|
This is a Module::Install extension that helps users who do not have root |
65
|
|
|
|
|
|
|
access to install modules. It first prompts the user for a normal installation |
66
|
|
|
|
|
|
|
into the default Perl paths, or a custom installation. If the user selects a |
67
|
|
|
|
|
|
|
custom installation, it prompts the user for the value for PREFIX. This value |
68
|
|
|
|
|
|
|
is then used to add PREFIX=value to @ARGV. |
69
|
|
|
|
|
|
|
|
70
|
|
|
|
|
|
|
If the user specifies PREFIX or INSTALLDIRS as arguments to Makefile.PL, then |
71
|
|
|
|
|
|
|
the prompts are skipped and a normal installation is done. |

=head1 COMPATIBILITY NOTE |
75
|
|
|
|
|
|
|
|
76
|
|
|
|
|
|
|
Consider carefully whether you want to use this module. In my experience, many |
77
|
|
|
|
|
|
|
people don't want an interactive installation. For example, CPAN users have |
78
|
|
|
|
|
|
|
likely already thought about custom installation paths. Debian package |
79
|
|
|
|
|
|
|
maintainers also want non-interactive installs. |

Imported into Makefile.PL by Module::Install when invoked. This causes the |

|
|
|
|
|
prompts to be displayed and @ARGV to be updated (if necessary). |
