## Command Line usage

Usage is simple: `ncp [source] [dest] [--limit=concurrency limit]
[--filter=filter] --stopOnErr`
[--filter=filter] [--dereference] --stopOnErr`

The 'filter' is a Regular Expression - matched files will be copied.

The 'concurrency limit' is an integer that represents how many pending file system requests `ncp` has at a time.

'dereference' is a boolean flag that will tell `ncp' to follow symbolic links.

'stoponerr' is a boolean flag that will tell `ncp` to stop immediately if any
errors arise, rather than attempting to continue while logging errors. The default behavior is to complete as many copies as possible, logging errors along the way.
