* Proposal for less redundant argument handling, autopep8, sorted imports, etc.
* dest labels in sync with local target vars and safe names
* only one special handling before transfer of values to local vars (headers prompt)
* some initial comments - there was a quest for help on documentation ;-)
* few oneliners from if else variable setters
* left the simple script style as is (might be a preference for author and users)
* Adapted code for static checks and removed unused mports sys and requests, many unused variables remain
