Description :
Have you ever wished for your installation shell scripts to run reproducibly, without much programming fuzz, and even with optional logging enabled? Then give up shell programming, use Perl.
\'Sysadm::Install\' executes shell-like commands performing typical installation tasks: Copying files, extracting tarballs, calling \'make\'. It has a \'fail once and die\' policy, meticulously checking the result of every operation and calling \'die()\' immediately if anything fails.
\'Sysadm::Install\' also supports a _dry_run_ mode, in which it logs everything, but suppresses any write actions. Dry run mode is enabled by calling \'Sysadm::Install::dry_run(1)\'. To switch back to normal, call \'Sysadm::Install::dry_run(0)\'.
As of version 0.17, \'Sysadm::Install\' supports a _confirm_ mode, in which it interactively asks the user before running any of its functions (just like \'rm -i\'). _confirm_ mode is enabled by calling \'Sysadm::Install::confirm(1)\'. To switch back to normal, call \'Sysadm::Install::confirm(0)\'.
\'Sysadm::Install\' is fully Log4perl-enabled. To start logging, just initialize \'Log::Log4perl\'. \'Sysadm::Install\' acts as a wrapper class, meaning that file names and line numbers are reported from the calling program\'s point of view.
