Clarified script and edited man page
Hello and thank you for the nice tool! I had some trouble understanding
the usage due to some discrepancies with the man page or comments and
the code.
I believe this small patch will help new users (like me) to not be
confused.
- The flags in usage() still showed [-n], this is no longer used
- Removed inaccurate reference to dry-run in man page
- Missing reference to 3rd arg in comments of copy_files()
Preserve time of copied files
Exit when temporary directory can't be created
Drist now supports looping over hostname list or a file containing hostnames
Add CHANGELOG file to keep track of changes
drist wasn't preserving permissions on files with rsync
Add -p flag for persistent connections through the script
enhance visual of copied file list
