Copies specified line numbers from one text file to another. It is
written in C# so it requires the .NET Framework.
LCOPY [-input ] [-output ]
[-start ] [-stop ]
[-help] [-silent]
Example: lcopy -start 2 -input in.txt -output out.txt
The above example copies lines #2 thru EOF from in.txt to out.txt.
If -input is omitted, LCOPY uses STDIN.
If -output is omitted, LCOPY uses STDOUT.
If -start is omitted, LCOPY starts with line #1.
If -stop is omitted, LCOPY stops at EOF.
