Application will watch directory for text files to be created or modified in a directory and

then output information about them.

The program takes 2 arguments, the directory to watch and a file pattern, example: program.exe "c:\file folder" *.txt

The path may be an absolute path, relative to the current directory, or UNC.

Use the modified date of the file as a trigger that the file has changed.

Check for changes every 10 seconds.

When a file is created output a line to the console with its name and how many lines are in it.

When a file is modified output a line with its name and the change in number of lines (use a + or - to indicate more or less).

When a file is deleted output a line with its name.

Files will be ASCII or UTF-8 and will use Windows line separators (CR LF).

Multiple files may be changed at the same time, can be up to 2 GB in size, and may be locked for several seconds at a time.

Use multiple threads so that the program doesn't block on a single large or locked file.

Program will be run on Windows OS.

File names are case insensitive.
