49             =head1 NAME
50              
51             Module::Install::CustomInstallationPath - A Module::Install extension that allows the user to interactively specify custom installation directories
52              
53              
54             =head1 SYNOPSIS
55              
56             In Makefile.PL:
57             use inc::Module::Install;
58             ...
59             check_custom_installation();
60              
61              
62             =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.
72              
73              
74             =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.

85             =item check_custom_installation()
86              
87             Imported into Makefile.PL by Module::Install when invoked. This causes the
88             prompts to be displayed and @ARGV to be updated (if necessary).
