23 CPAN::FirstTime - Utility for CPAN::Config file Initialization
27 CPAN::FirstTime::init()
31 The init routine asks a few questions and writes a CPAN::Config
32 file. Nothing special.

57 CPAN is the world-wide archive of perl resources. It consists of about
58 100 sites that all replicate the same contents all around the globe.
59 Many countries have at least one CPAN site already. The resources
60 found on CPAN are easily accessible with the CPAN.pm module. If you
61 want to use CPAN.pm, you have to configure it properly.
63 If you do not want to enter a dialog now, you can answer 'no' to this
64 question and I\'ll try to autoconfigure. (Note: you can revisit this
65 dialog anytime later by typing 'o conf init' at the cpan prompt.)

90 The following questions are intended to help you with the
91 configuration. The CPAN module needs a directory of its own to cache
92 important index files and maybe keep a temporary mirror of CPAN files.
93 This may be a site-wide directory or a personal directory.
97 my $cpan_home = $CPAN::Config->{cpan_home} || MM->catdir($ENV{HOME}, ".cpan");
101 I see you already have a directory
103 Shall we use it as the general CPAN build and cache directory?
109 First of all, I\'d like to create this directory. Where?
114 $default = $cpan_home;

125 warn "Couldn't find directory $ans
126 or directory is not writable. Please retry.\n";
129 $CPAN::Config->{cpan_home} = $ans;
133 If you want, I can keep the source files after a build in the cpan
134 home directory. If you choose so then future builds will take the
135 files from there. If you don\'t want to keep them, answer 0 to the

141 $CPAN::Config->{build_dir} = MM->catdir($CPAN::Config->{cpan_home},"build");
144 # Cache size, Index expire
149 How big should the disk cache be for keeping the build directories
150 with all the intermediate files?

163 By default, each time the CPAN module is started, cache scanning
164 is performed to keep the cache size in sync. To prevent from this,
165 disable the cache scanning with 'never'.
169 $default = $CPAN::Config->{scan_cache} || 'atstart';

176 # prerequisites_policy
177 # Do we follow PREREQ_PM?
181 The CPAN module can detect when a module that which you are trying to
182 build depends on prerequisites. If this happens, it can build the
183 prerequisites for you automatically ('follow'), ask you for
184 confirmation ('ask'), or just ignore them ('ignore'). Please set your
185 policy to one of the three values.
189 $default = $CPAN::Config->{prerequisites_policy} || 'follow';

203 The CPAN module will need a few external programs to work
204 properly. Please correct me, if I guess the wrong path for a program.

297 Sometimes you may wish to leave the processes run by CPAN alone
298 without caring about them. As sometimes the Makefile.PL contains
299 question you\'re expected to answer, you can set a timer that will
300 kill a 'perl Makefile.PL' process after the specified time in seconds.
