Quick and Dirty Recursive File Regex Counter

regexFiles.py

'''
Brief:
    This searchs a directory recursively (by default the current directory) for a given regex match. The total number of matches is counted and printed at the end.   
    By default, it looks for lines where the author tag is given but there is no name provided.
