Perl is easy to write, starts up relatively quickly, and has a lot of
available modules for specific operations. Since it interpreted as
plain text, you can include a file with the full syntax available for
configuration instead of having to writing your own parser with
yet-another-syntax for config files. But, it is somewhat hard to scale
and maintain because people write in different styles and things that
start small tend to have a lot of global variables that are hard to
remember as the code grows. And perl is not great for GUI programs.
I'd consider backuppc (which contains a nearly complete rsync
implementation) and RT (a trouble-ticket system) to be ambitious
projects for perl.
For larger scale things, look at java. Examples might be OpenNMS,
Hudson, OpenGrok, or Alfresco. These are long-running servers where the
startup time is not a problem and in Hudson's case the cross-platform
compatibility is a big plus because a master program can schedule and
distribute jobs across many different types of machines.
