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)'.
