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

52 The CPAN module needs a directory of its own to cache important
53 index files and maybe keep a temporary mirror of CPAN files. This may
54 be a site-wide directory or a personal directory.
57 my $cpan_home = $CPAN::Config->{cpan_home} || MM->catdir($ENV{HOME}, ".cpan");
61 I see you already have a directory
63 Shall we use it as the general CPAN build and cache directory?
69 First of all, I\'d like to create this directory. Where?

88 If you want, I can keep the source files after a build in the cpan
89 home directory. If you choose so then future builds will take the
90 files from there. If you don\'t want to keep them, answer 0 to the

123 properly. Please correct me, if I guess the wrong path for a program.

151 Every Makefile.PL is run by perl in a separate process. Likewise we
152 run \'make\' and \'make install\' in processes. If you have any parameters
153 \(e.g. PREFIX, INSTALLPRIVLIB, UNINST or the like\) you want to pass to
154 the calls, please specify them here.

176 Sometimes you may wish to leave the processes run by CPAN alone
177 without caring about them. As sometimes the Makefile.PL contains
178 question you\'re expected to answer, you can set a timer that will
179 kill a 'perl Makefile.PL' process after the specified time in seconds.
181 If you set this value to 0, these processes will wait forever. This is
182 the default and recommended setting.
