This is a simple program that takes a few arguments. First, give the program the file type you want to search for. And example would be go. This would count all the files that end with .go. Then, you give it a directory to search, such as path/to/directory. The program will then search the directory, and count every line in every file that has the correct file type.

You can also give line counter multiple fileTypes to search, such as js, html, and css. Here are some example queries:

> lc go C:/Users/Documents/Code/Go/MyProject
Total: 500 with 0 errors.

> lc js html css ../../JavaScript/MyWebsite
Total: 78 with 1 errors.

Another feature is the -details flag. By using this flag you will get per-file line amounts.
