"""
Given a type of integer (positive non-zero <= 10,000, negative 
 non-zero >= -10,000, all) and the names of one or more files of strings 
 (all of which need not be integers) as command-line arguments, computes 
 and prints the number, total, minimum, and maximum of all integers of the 
 requested type in the specified files.

Note that range-checking in function getIntList() is now implemented
 with default lower and upper bounds.
