-=====
+logcp - Bulk Copy with Manual Interface
+=======================================
 
-Performs bulk copy operations allowing users to manually remap source objects to destinations
+This script looks at some number of most-recently-modified files in a source
+directory and copies them to a destination allowing the user to direct the
+objects to manually-defined deestination directories as they pass through.
+
+I find this useful for handling stuff like log files and backups.
+
+Syntax: `logcp [num]` where `num` can optionally be how far back to go back in
+the recent files to import.  At this point, an editor will open up with the
+opportunity to say where the folder will go according to the screenshot below.
+
+Configure the variables in `example.cfg` first and save that file as
+`~/.logcp.cfg`.
