  FAQ's

 

  Why Did You Make This?

 

  I made this project to demonstrate my PERL coding skills and that YES, when I say

  I have 15+ years work experience in industry, I really do know how to make a 

  project work. I have made many more PERL scripts for my employers and consulting

  clients to download data from databases, manipulate, report, and or transmit to

  other databases, the Internet, and computer modeling applications. I achieved this

  project working independently as the sole developer and IT solutions engineer.

  

  I See Code Improvments and Ideas, Can I Contribute?

 

  Yes, there are a plenty ways to make this script better. I do not have time

  or interest to discuss and address every comment. I do not plan to

  make frequent, if any, updates to this project. You may make your own code

  project sites and grow the knowledge community. 

 

  License, Terms of Use?

 

  You may use, modify, or learn from this script to help you with your next PERL project 

  either for school or company projects. 

  Be fruitful with your PERL, prosper, and contribute to the knowledge community.
