Mornin' (composed before coffee) --
First Question: Industry -- any industry that uses IT can use Perl. Most of them do.
Second Question: Applications -- many and varied; almost as many different applications as there are Industries. There are some common applications: text manipulation, system administration, data validation, Web services, bug tracking, content management, to name a few
Third Question: Overlap -- yes. See previous paragraph
Fourth Question: Doc -- Yes there are. Most of them can be found with your Search Engine of choice; search on 'field name' + perl.
Now, I go down stairs and get me some coffee and breakfast.

I Go Back to Sleep, Now.
