# Read from standard input a list of filenames, and
# report a sorted list of extensions and filenames
# (most common ones first).
# The format is "name count", where "count" is the number of appearances.
# "name" usually begins with a "." followed by the name of the extension.
# In the case where the filename has no extension, the name begins with "/"
# followed by the entire basename.
# This is part of SLOCCount, a toolsuite that counts
# source lines of code (SLOC).
