1  This program is being tested with Python 3.8
 2  
 3  The purpose of this program is to allow files to be successfully copied from
 4  a source, or multiple sources to a single destination insuring that the same
 5  file is never copied twice and that a file on the destination is never overwritten.
 6  The program allows the user to specify a source (one at a time), a destination, and
 7  and a list of file types to ignore, in which case all files not matching the list are
 8  checked for potential copy/sync, or a list of file types to include, in which case
 9  only the files mathing the selected file type are checked for potential copy.

11  If you are like me and you have multiple HDDs/SSDs/CDs laying around for years and
12  need to get everything organized, space freed up on multiple devices, and disks discarded.
13  That is is the purpose of this program.

15  Here is an example of running this program (eventually a shabang will be added and .py removed from the main program):
16  gsync.py ./testing/source ./testing/destination --file_types documents
17  
18  Here are the current options being tested with:
19  ./testing/source ./testing/destination --file_types documents
